#### 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](https://redirect.github.com/dtolnay/thiserror/issues/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.
```rust
#[derive(Error, Debug)]
#[error("... {type} ...")] // Before: {r#type}
pub struct Error {
pub r#type: Type,
}
```
- Trait bounds are no longer inferred on fields whose value is shadowed
by an explicit named argument in a format message
([#​345](https://redirect.github.com/dtolnay/thiserror/issues/345))
```rust
// Before: impl<T: Octal> Display for Error<T>
// After: impl<T> Display for Error<T>
#[derive(Error, Debug)]
#[error("{thing:o}", thing = "...")]
pub struct Error<T> {
thing: T,
}
```
- 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](https://redirect.github.com/dtolnay/thiserror/issues/354))
```rust
#[derive(Error, Debug)]
#[error("ambiguous: {0} {}", $N)]
// ^^^ Not allowed, use #[error("... {0} {n}", n = $N)]
pub struct TupleError(i32);
```
- Code containing invocations of thiserror's `derive(Error)` must now
have a direct dependency on the `thiserror` crate regardless of the
error data structure's contents
([#​368](https://redirect.github.com/dtolnay/thiserror/issues/368),
[#​369](https://redirect.github.com/dtolnay/thiserror/issues/369),
[#​370](https://redirect.github.com/dtolnay/thiserror/issues/370),
[#​372](https://redirect.github.com/dtolnay/thiserror/issues/372))
#### Features
- Support disabling thiserror's standard library dependency by disabling
the default "std" Cargo feature: `thiserror = { version = "2",
default-features = false }`
([#​373](https://redirect.github.com/dtolnay/thiserror/issues/373))
- Support using `r#source` as field name to opt out of a field named
"source" being treated as an error's `Error::source()`
([#​350](https://redirect.github.com/dtolnay/thiserror/issues/350))
```rust
#[derive(Error, Debug)]
#[error("{source} ==> {destination}")]
pub struct Error {
r#source: char,
destination: char,
}
let error = Error { source: 'S', destination: 'D' };
```
- Infinite recursion in a generated Display impl now produces an
`unconditional_recursion` warning
([#​359](https://redirect.github.com/dtolnay/thiserror/issues/359))
```rust
#[derive(Error, Debug)]
#[error("??? {self}")]
pub struct Error;
```
- A new attribute `#[error(fmt = path::to::myfmt)]` can be used to write
formatting logic for an enum variant out-of-line
([#​367](https://redirect.github.com/dtolnay/thiserror/issues/367))
```rust
#[derive(Error, Debug)]
pub enum Error {
#[error(fmt = demo_fmt)]
Demo { code: u16, message: Option<String> },
}
fn demo_fmt(code: &u16, message: &Option<String>, formatter: &mut
fmt::Formatter) -> fmt::Result {
write!(formatter, "{code}")?;
if let Some(msg) = message {
write!(formatter, " - {msg}")?;
}
Ok(())
}
```
- Enums with an enum-level format message are now able to have
individual variants that are `transparent` to supersede the enum-level
message
([#​366](https://redirect.github.com/dtolnay/thiserror/issues/366))
```rust
#[derive(Error, Debug)]
#[error("my error {0}")]
pub enum Error {
Json(#[from] serde_json::Error),
Yaml(#[from] serde_yaml::Error),
#[error(transparent)]
Other(#[from] anyhow::Error),
}
```
