Enum RegexCompileError 

pub enum RegexCompileError {
    InvalidSyntax(String),
    UnsupportedFeature(String),
    DepthExceeded {
        limit: usize,
    },
    EmptyPattern,
    InvalidUtf8(String),
}

Errors arising from compiling a regex pattern into a Grammar.

Variants

InvalidSyntax(String)

The regex pattern has a syntax error.

UnsupportedFeature(String)

The pattern uses a feature not supported by this compiler.

DepthExceeded

The DFA state count or NFA expansion exceeded an internal limit.

Fields

limit: usize

The exceeded limit.

EmptyPattern

The pattern is the empty string.

InvalidUtf8(String)

The pattern contains invalid UTF-8 byte sequences where UTF-8 is required.

Trait Implementations

impl Clone for RegexCompileError

fn clone(&self) -> RegexCompileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegexCompileError

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

Formats the value using the given formatter.

impl Display for RegexCompileError

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

Formats the value using the given formatter.

impl Error for RegexCompileError

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 PartialEq for RegexCompileError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
