Struson 0.5.0

Changes

• Added support for trailing comma for json_path!
• Fixed json_path! not using full type path when creating empty array
  (could probably have lead to compilation errors if JsonPathPiece had not been imported)
• Fixed UnexpectedStructureKind::to_string not including field values
• Added JsonReader::seek_back as opposite of seek_to (#53)

Simple API

• (Breaking) Removed structs ArrayItemReader and MemberValueReader in favor of the new common struct SingleValueReader
• Reader and writer will keep returning errors after the first error (#55)
  This is intended as safeguard in case an error is accidentally not propagated by a closure or function provided by the user. However, users should not rely on this behavior, and instead use Rust's ? operator for propagating reader and writer errors.
• New ValueReader methods:
  • read_str for reading a JSON string value as borrowed str
  • read_seeked and read_seeked_multi for making it easier to seek to values and read them (#48, #49)
    Especially read_seeked_multi can be quite useful for reading for example all values of nested JSON arrays or objects; see its documentation for examples.
  • read_string_with_reader for reading large string values in a streaming way (#54)
• New ValueWriter methods:
  • write_string_with_writer for writing large string values in a streaming way (#54)

Struson 0.4.1

Changes

Serde serialization:

• Fixed spurious SerializerError::IncorrectElementsCount when skipping fields (#41)

Struson 0.4.0

Breaking changes

• Marked some error enum types as non_exhaustive
• struson::serde::DeserializerError enum variants ParseIntError and ParseFloatError have been replaced with new variant InvalidNumber
• ReaderError::IoError variant has been changed to a struct which now includes the error location
• Improved JsonErrorLocation structure; renamed it to JsonReaderPosition
• Changed return type of JsonReader::next_string_reader and JsonWriter::string_value_writer to use impl Trait (#18)
  When using those methods it might be necessary to add additional use declarations for Read and for Write and StringValueWriter.

Major changes

• Experimental "simple API" (#34)
  API enforces correct usage at compile time, instead of panicking at runtime (as done by JsonReader and JsonWriter).
  Feedback is highly appreciated!

Changes

• Adjusted Serde integration to match serde_json 1.0.111 behavior (with some minor differences)
• JsonStreamReader now keeps retrying to read data in case an error of kind ErrorKind::Interrupted occurs
  This is consistent with the current behavior of JsonStreamWriter, and avoids reading potentially incorrect data when using default methods such as Read::read_exact on the string value reader returned by JsonReader::next_string_reader().
• Improve string value reader (JsonReader::next_string_reader()) and string value writer (JsonWriter::string_value_writer()) error behavior
  Now when an error occurs, any subsequent read and write attempts will return an error as well.
• Included Cargo.lock in repository
• Fixed line number for TrailingCommaNotEnabled syntax error being incorrect if line breaks are after comma
• Added tracking of byte position for JsonStreamReader
• Added JsonReader::current_position(...) method for obtaining the current position of the JSON reader (#14)
• Added JsonStreamReader::reader_mut() for obtaining reference to underlying reader (#25)
• Added nesting limit for JsonStreamReader (#28)
• Added support for no arguments for json_path!

Struson 0.3.0

Breaking changes

• Changed number traits used by JsonWriter methods number_value and fp_number_value
  This most likely only affects custom JsonWriter implementations. See below for details.

Changes

• Fixed JsonStreamReader::next_name sometimes returning wrong results (#10)
• Added StringValueWriter::write_str
• Tried to improve number reading and number string writing performance
• Tried to improve JsonStreamReader::transfer_to performance for string values
• Adjusted number traits used by JsonWriter methods number_value and fp_number_value
  These changes are mainly relevant for custom implementations of JsonWriter.
  • IntegralNumber has been renamed to FiniteNumber to better describe its behavior
  • Number traits no longer have ToString and Copy as supertraits; instead they have a new use_json_number method to consume a str
  • Number traits have new methods to obtain the value as u64 / i64, respectively f64

Struson 0.2.0

Breaking changes

• Removed ReaderSettings::update_path_during_skip; use the new ReaderSettings::track_path to completely disable path tracking instead
• The return type of JsonReader::next_name has changed from String to str; use the new method next_name_owned to directly obtain a String

Changes

• Added ReaderSettings::track_path to allow disabling path tracking for better performance
• Added JsonReader methods for reading values as str; if only a str is needed these methods will be more performant memory-wise than the methods returning a String
  • next_name (the existing next_name method has been renamed to next_name_owned)
  • next_str
  • next_number_as_str
