Each one modifies an
existing diagnostic, either in a standalone fashion, e.g.
err.code(code);, or in a chained fashion to make multiple modifications,
e.g. err.code(code).span(span);.Diag Used for emitting structured error messages and other diagnostic information.
Wraps a DiagInner, adding some useful things. DiagDecorator Type used to emit diagnostic through a closure instead of implementing the Diagnostic trait. DiagInner The main part of a diagnostic. Note that Diag, which wraps this type, is
used for most operations, and should be used instead whenever possible.
This type should only be used when Diag’s lifetime causes difficulties,
e.g. when storing diagnostics within DiagCtxt. DiagLocation DiagStyledString IsLint StringPart Subdiag A “sub”-diagnostic attached to a parent diagnostic.
For example, a note attached to an error. Diagnostic Trait implemented by error types. This is rarely implemented manually. Instead, use
#[derive(Diagnostic)] – see rustc_macros::Diagnostic . Subdiagnostic Trait implemented by error types. This should not be implemented manually. Instead, use
#[derive(Subdiagnostic)] – see rustc_macros::Subdiagnostic .
