AhoCorasick(BuildError)

Aho-Corasick build failed.

RegexTooLarge

Regex pattern exceeded the configured hard limit.

Fields

id: usize

Pattern ID.

max_bytes: usize

Maximum allowed byte length.

TooManyRegexPatterns

Too many regex patterns were supplied.

Fields

count: usize

Actual regex pattern count.

max: usize

Maximum supported regex pattern count.

Empty

No patterns provided.

Trait Implementations

impl Debug for MatchError

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

Formats the value using the given formatter.

impl Display for MatchError

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

Formats the value using the given formatter.

impl Error for MatchError

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.
