Struct MutationCaptureError 

pub struct MutationCaptureError(/* private fields */);

How one mutation helper body was not read.

Its own type, because a diagnostic’s family tag is a fact about the type: this grammar is a declaration’s SECOND helper reading, and the trial grammar is its first.

Implementations

impl MutationCaptureError

pub const fn grammar_refused( grammar: Grammar, cause: CaptureCause, at: SpanHandle, ) -> Self

One refusal the mutation grammar’s own reading established.

pub const fn vocabulary_refused( grammar: Grammar, refusal: DeclarationError, at: SpanHandle, ) -> Self

One refusal the vocabulary established over a value this grammar read.

pub const fn refusal(&self) -> &HelperRefusal

The refusal itself.

Trait Implementations

impl Eq for MutationCaptureError

impl Error for MutationCaptureError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
