Enum MatcherError 

#[non_exhaustive]
pub enum MatcherError {
    IllegalToken {
        token: TokenId,
    },
    ArtifactMismatch,
}

A runtime matcher error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IllegalToken

A token was fed that the matcher cannot legally consume (dead/no transition).

Fields

token: TokenId

The rejected token id.

ArtifactMismatch

A cached artifact did not match its expected fingerprint.

Trait Implementations

impl Clone for MatcherError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MatcherError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MatcherError

impl Eq for MatcherError

impl Error for MatcherError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<MatcherError> for SessionError

fn from(e: MatcherError) -> Self

Converts to this type from the input type.

impl PartialEq for MatcherError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
