Up until now,
IgnoreEmpty
will make copier ignore all zero value and nil fields. Sometimes you still want certain fields to be overridden though. This will make it so that if you set thecopier:"override"
tag, the field will be copied in every single case even ifIgnoreEmpty
is set to true. It's a convenient addition for more granular control over which fields should be copied or not.I've also updated the docs so that the usage is clearer. This means there are usage examples for all the supported cases, including a little reference at the end with all supported tags.
