0.5.0 - 2020-01-25

on GitHub

Changed

• [BREAKING] Move doc and skip into a subsetting named setter(...).
  This means that #[builder(doc = "...")], for example, should now be written
  as #[builder(setter(doc = "..."))].
• [BREAKING] Setter arguments by default are no longer automatically
  converted to the target type with into(). If you want to automatically
  convert them, use #[builder(setter(into))]. This new default enables rustc
  inference for generic types and proper integer literal type detection.
• Improve build errors for incomplete .build() and repeated setters, by
  creating faux methods with deprecation warnings.

Added

• #[builder(setter(strip_option))] for making setters for Option fields
  automatically wrap the argument with Some(...). Note that this is a weaker
  conversion than #[builder(setter(into))], and thus can still support type
  inference and integer literal type detection.

Removed

• [BREAKING] Removed the default_code setting (#[builder(default_code = "...")]) because it is no longer required now that Rust and syn support
  arbitrary expressions in attributes.
