[dependabot]

Bumps bon from 2.3.0 to 3.1.0.

Release notes

Sourced from bon's releases.

v3.1.0

Added

• Add #[builder(field)] to define custom private fields on the builder type. See Custom Fields guide for details (#207)

Other

• Internal refactoring of naming in bons test suite (#215)

v3.0.2

Fixed

• Fix unexpected_cfgs lint coming from #[cfg(rust_analyzer)] on the latest nightly (#212)

v3.0.1

Fixed

• Fix handling of lifetimes not used in fn param types (#208)

v3.0.0

See the most interesting changes described in Bon 3.0 Release blog post.

All the breaking changes are very unlikely to actually break your code that was written against the v2 version of bon. 99% of users should be able to update without any migration.

Changed

• 🎉🎉 Stabilize the builder's typestate API allowing for custom builder extensions. This is the main theme of this release. This new API brings the flexibility to a whole new level 🚀 🚀 (#145)

• Improve rustdoc output. See the rustoc examples and comparison in the Alternatives section (#145)

  • Add info that the member is required or optional.

  • For members with default values show the default value in the docs.

  • For optional members provide links to {member}(T) and maybe_{member}(Option<T>) setters.

  • Remove __ prefixes for generic types and lifetimes from internal symbols. Instead, the prefixes added only if the macro detects a name collision.

• ⚠️ Breaking. Reject unnecessary empty attributes e.g. #[builder()] or #[builder] with no parameters on a member (#145)

• ⚠️ Breaking. Reject square brackets and curly braces delimiters for builder_type, finish_fn, start_fn and on attributes syntax. Only parentheses are accepted e.g. #[builder(finish_fn(...))] or #[builder(on(...))]. This no longer works: #[builder(finish_fn[...])] or #[builder(on{...})] (#145)

• ⚠️ Breaking. Reject non-consecutive on(...) clauses. For example, the following now generates a compile error: #[builder(on(String, into), finish_fn = build, on(Vec<_>, into))], because there is a finish_fn = ... between on(...) clauses. (#155)

• ⚠️ Breaking. #[builder(derive(Clone, Debug))] now generates impl blocks that follow the behaviour of standard Clone and Debug derives in that it conservatively adds Clone/Debug trait bounds for all the generic types declared on the original item (struct or function). Previously no additional bounds were required on Clone and Debug impls. See the Added section for details on the way to override these bounds with #[builder(derive(Clone/Debug(bounds(...))))] (#145)

• ⚠️ Breaking. The name of the builder struct generated for methods named builder changed from TBuilderBuilder to just TBuilder making methods named builder work the same as methods named new. (#145)

• ⚠️ Breaking. The type of the builder is now dependent on the order of the setters' invocation. This may only break code like the following:
