Breaking changes
Referencing keyword-named fields by a raw identifier like
{r#type}
inside a format string is no longer accepted; simply use the unraw name like{type}
(#347)This aligns thiserror with the standard library's formatting macros, which gained support for implicit argument capture later than the release of this feature in thiserror 1.x.
Trait bounds are no longer inferred on fields whose value is shadowed by an explicit named argument in a format message (#345)
Tuple structs and tuple variants can no longer use numerical
{0}
{1}
access at the same time as supplying extra positional arguments for a format message, as this makes it ambiguous whether the number refers to a tuple field vs a different positional arg (#354)Code containing invocations of thiserror's
derive(Error)
must now have a direct dependency on thethiserror
crate regardless of the error data structure's contents (#368, #369, #370, #372)Features
Support disabling thiserror's standard library dependency by disabling the default "std" Cargo feature:
thiserror = { version = "2", default-features = false }
(#373)Support using
r#source
as field name to opt out of a field named "source" being treated as an error'sError::source()
(#350)Infinite recursion in a generated Display impl now produces an
unconditional_recursion
warning (#359)A new attribute
#[error(fmt = path::to::myfmt)]
can be used to write formatting logic for an enum variant out-of-line (#367)Enums with an enum-level format message are now able to have individual variants that are
transparent
to supersede the enum-level message (#366)v1.0.68
