Enum RegexDfaError 

#[non_exhaustive]
pub enum RegexDfaError {
    RegexCompile(RegexCompileError),
    DfaBudgetExceeded {
        message: String,
    },
    EmptyPatternSet,
}

Error type for RegexDfaPipeline compilation failures.

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.

RegexCompile(RegexCompileError)

The regex set failed NFA compilation (syntax error, unsupported feature, or NFA state cap exceeded).

DfaBudgetExceeded

The DFA subset construction exceeded the state budget.

Fields

message: String

Human-readable description of the budget failure.

EmptyPatternSet

The pattern set is empty - nothing to compile.

Trait Implementations

impl Clone for RegexDfaError

fn clone(&self) -> RegexDfaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegexDfaError

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

Formats the value using the given formatter.

impl Display for RegexDfaError

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

impl Error for RegexDfaError

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<RegexCompileError> for RegexDfaError

fn from(err: RegexCompileError) -> Self

Converts to this type from the input type.
