v3.6.3

Fixed

• Fix missing support for #[builder(field)] with #[builder(const)] (#291)

v3.6.2

Added

• Propagate #[target_feature] attributes on #[builder]-generated finishing functions (#284). Thanks @Lilyyy411 for the contribution!

Fixed

• Fix visibility and const token order in code generated by #[builder(const)] (#288)

v3.6.1

Fixed

• Propagate #[track_caller] to the generated finishing function from the underlying function/method (#282). Thanks @Lilyyy411 for the contribution!

v3.6.0

Added

• Add very limited support for #[builder(const)] (#279).
  See the updated docs here

v3.5.2

Fixed

• Small fix for rust-analyzer syntax highlighting of parameters for functions annotated with #[builder] (#275).
  This doesn't fix the problem fully since function parameters are now assigned "variable" semantic token type instead of "parameter". However, it's already better than "struct" that they were assigned before this fix. Created an issue in rust-analyzer with more details and to get the full fix of this problem: rust-lang/rust-analyzer#19556.
• Fix lints on nightly 2025-03-20 (#272)

v3.5.1

Fixed

• Delay the privatizing (i.e. renaming of the original function to __orig_{fn_name}) until after all other macros are expanded (#269). Also removed the warnings for #[tracing::instrument] users introduced in #264. This is because with this patch there will be no difference whether you place #[tracing::instrument] after or before the #[builder] attribute - all other proc macros on the function will see the original function name.

v3.5.0

Added

• Introduce setters(doc(default(skip))) attribute to skip the inclusion of the default value in the generated docs for setters (#265). See the updated docs here.

Fixed

• Trigger a compiler warning if #[tracing::instrument] is placed after the #[builder] instead of before (#264). This should prevent the papercut where tracing::instrument assigns the span name with the ugly __orig_ prefix in the name.
• Fix repeated #[builder] attributes getting ignored on free functions (#263)

v3.4.0

Added

• Stabilize the current #[builder(getter)] attribute MVP (#251).
  The cargo feature experimental-getters is no longer needed and is now no-op.
• Make self receiver and start_fn members available as official fields on the builder (#250).
  Check the new documentation page about native fields.
• Introduce #[builder(derive(Into))] attribute to generate an impl From<Builder> for T (#248).
  See the updated "Inspecting" guide page now known as Derives for Builders and the updated #[builder(derive)] reference.
