[Unreleased]
2.3.0 - 2024-09-14
See the blog post for this release that describes some of the most notable changes in detail.
Added
- Add support for positional params in
start_fn
andfinish_fn
(#125)
Fixed
- Forward lint suppression from
#[allow()/expect()]
attributes written by the user on the top-level to the generated items (#125) - Suppress the false-positive (clippy issue)
clippy::future_not_send
lint (#125) - Fix the cases where
#[builder(derive(Debug, Clone))]
didn't validate for all members to implementClone/Debug
if these members were of reference or generic types (#125)
2.2.1 - 2024-09-09
Changed
- Lower MSRV from 1.70.0 to 1.59.0 (#120)
2.2.0 - 2024-09-08
See the blog post for this release that describes some of the most notable changes in detail.
Changed
The
#[bon::builder]
attribute was deprecated on structs. The new#[derive(bon::Builder)]
should be used to derive a builder from a struct. Starting withbon
2.3 (next minor release) all usages of#[bon::builder]
on structs will generate deprecation warnings. (#99).There is a CLI to assist in migrating to the new syntax. See the release blog post for details about that.
Added
Add the top-level
#[builder(derive(...))]
attribute to be able to deriveClone
andDebug
for the builder type itself (#113)Add support for conditional compilation with
cfg/cfg_attr
(#99)
Fixed
- Fix developer experience in Rust Rover. The new
#[derive(Builder)]
syntax should now be easier for Rust Rover to analyze (#99) - Fix a bug where a member of opaque
Option
type (i.e. theOption
type that was renamed to make the builder macro not detect it asOption
) was still optional. (#99) - Fix code generation for structs with default values for generic parameters (#108)
2.1.1 - 2024-09-03
Added
- Set MSRV to 1.70.0. Note that we plan to set an even lower MSRV. This is just an initial attempt to define the MSRV that should be good enough in the meantime while we work on lowering it even more (#101)
Fixed
- Fix lints triggered by generated code such as
private_bounds
,clippy::missing_const_for_fn
(#101) - Add more context to the messages such that it's clear what member isn't set in Rust Analyzer error messages (#98)
