…erenity-rs#2646) This avoids having to allocate to store fixed length (replaced with normal array) or fixed capacity (replaced with `ArrayVec`) collections as vectors for the purposes of putting them through the `Request` plumbing. Slight behavioral change - before, setting `params` to `Some(vec![])` would still append a question mark to the end of the url. Now, we check if the params array `is_empty` instead of `is_some`, so the question mark won't be appended if the params list is empty.

This trades a heap allocation for messages sent along with thread creation for `Message`'s inline size dropping from 1176 bytes to 760 bytes,
…l models (serenity-rs#2656) This shrinks type sizes by a lot; however, it makes the user experience slightly different: - `FixedString` must be converted to String with `.into()` or `.into_string()` before it can be pushed to, but dereferences to `&str` as is. - `FixedArray` must be converted to `Vec` with `.into()` or `.into_vec()` before it can be pushed to, but dereferences to `&[T]` as is. The crate of these types is currently a Git dependency, but this is fine for the `next` branch. It needs some basic testing, which Serenity is perfect for, before a release will be made to crates.io.
…s push over the limit (serenity-rs#2660)
…enity-rs#2668) This commit: - switches from `u64` to `i64` in `CreateCommandOption::min_int_value` and `CreateCommandOption::max_int_value` to accommodate negative integers in Discord's integer range (between -2^53 and 2^53). Values outside this range will cause Discord's API to return an error. - switches from `i32` to `i64` in `CreateCommandOption::add_int_choice` and `CreateCommandOption::add_int_choice_localized` to accommodate Discord's complete integer range (between -2^53 and 2^53). Values outside this range will cause Discord's API to return an error.
This cache was just duplicating information already present in `Guild::members` and therefore should be removed. This saves around 700 MBs for my bot (pre-`FixedString`). This has to refactor `utils::content_safe` to always take a `Guild` instead of`Cache`, but in practice it was mostly pulling from the guild cache anyway and this means it is more likely to respect nicknames and other information, while losing the ability to clean mentions from DMs, which do not matter.
`Embed::fields` previously had to stay as a `Vec` due to `CreateEmbed` wrapping around it, but by implementing `Serialize` manually we can overwrite the `Embed::fields` with a normal `Vec`, for a small performance hit on serialization while saving some space for all stored `Embed`s.
Simply missed these when finding and replacing.
This uses the `bool_to_bitflags` macro to remove boolean (and optional boolean) fields from structs and pack them into a bitflags invocation, so a struct with many bools will only use one or two bytes, instead of a byte per bool as is. This requires using getters and setters for the boolean fields, which changes user experience and is hard to document, which is a significant downside, but is such a nice change and will just become more and more efficient as time goes on.
…rs#2681) This swaps fields that store `Option<Int>` for `Option<NonMaxInt>` where the maximum value would be ludicrous. Since `nonmax` uses `NonZero` internally, this gives us niche optimisations, so model sizes can drop some more. I have had to include a workaround for [serenity-rs#17] in `optional_string` by making my own `TryFrom<u64>`, so that should be removable once that issue is fixed. [serenity-rs#17]: LPGhatguy/nonmax#17
A couple of clippy bugs have been fixed and I have shrunk model sizes enough to make `clippy::large_enum_variant` go away.
A discord bot library should not be using the tools reserved for low level OS interaction/data structure libraries.
Discord seems to internally default Ids to 0, which is a bug whenever exposed, but this makes ID parsing more resilient. I also took the liberty to remove the `From<NonZero*>` implementations, to prevent future headaches, as it was impossible to not break public API as we exposed `NonZero` in `*Id::parse`.
…nity-rs#2694) This, 1. shrinks the size of Request, when copied around, as it doesn't have to store the max capacity at all times 2. shrinks llvm-lines (compile time metric) for my bot in debug from `1,153,519` to `1,131,480` as no monomorphisation has to be performed for `MAX_PARAMS`.
Follow-up to serenity-rs#2694. When `Request::params` was made into an ArrayVec, the `Option` around it was removed in order to avoid having to add a turbofish on `None` to specify the value of `MAX_PARAMS`. Also, `Request::new` also needed to be changed so that the value of `MAX_PARAMS` could be inferred. Now that the field is a slice again, we can wrap it in `Option` again (at no cost to size, thanks to niche opts). We ensure we never store the redundant `Some(&[])` by checking for an empty slice and storing `None` instead. This way, we ensure we never read an empty slice out of the `Some` variant.
The instrument macros generate 2% of Serenity's release mode llvm-lines, and are proc-macros so hurt compile time in that way, so this limits them to opt-in. This commit also fixes the issues that the instrument macro was hiding, such as results that didn't ever error and missing documentation.
This signature is hard to use as `None` cannot infer the type of the generic. I also replaced `Option<u8>` with `Option<NonMaxU8>` as it's more efficient and will make the user think of the maximum value.
…nity-rs#2698) This removes inefficient `IntoIterator` generics and instead takes what is actually required. I also reworked `reorder_channels` to allow for keeping the generic, as it actually does only just need iterator semantics.
Previously, someone assumed that `Ratelimiter` was going to be cloned, so put a ton of `Arc`s everywhere. This was unneeded, and before dashmap, so the buckets were also stored massively inefficiently. This fixes all that. I had to shuffle around the `Ratelimit` methods a little bit to return their sleep time instead of sleeping themselves, so I didn't have to hold a dashmap lock over an `.await`.
This removes multiple error variants and overall cleans up the codebase by moving overflow checks into two `ModelError` variants.
Shrinks `size_of::<Error>` from 136 bytes to 64 bytes, while removing unused variants. This will improve performance for any method returning `Result<T>` where `T` is less than the size of `Error` as both `Result`'s `Ok` and `Err` have to be allocated stack space.
The compiler knows best as inlining is quite complicated. This should help with compile times, significantly.
This is possible now more methods are cache-less.
This avoids allocating instances of `serde_json::Value`s.
These were found by auditing .http() calls, instead of just manually looking at `impl CacheHttp`.
I currently working with wasm on one of my personal projects. I'm would like to use `serenity` to get access to the discord API response models, but currently the library can not the compiled to wasm, because the `tokio/fs` feature is not supported in that target. I went ahead and removed the need to include that feature by default. By the looks of it, it only was used with the `builder` and `model` features, so I conditionally added `tokio/fs` back when those features are being used (the `model` feature already depends on `builder` so that doesn't need to be changed).
This has to be on the next branch as reqwest is exposed in a couple places.
This announcement was missed (around August 2022) and probably the cause of a lot of the disconnections.
The documentation was never updated after serenity-rs#2662 removed the user cache.
This field is documented as nullable but that isn't reflected in the model. I also took the opportunity to replace the Option<Vec> with a default Vec.
This was mistakenly removed in serenity-rs#2278 and wasn't caught because of the wildcard pattern in the match.
