Enum GrepError 

pub enum GrepError {
    InvalidRegex(String),
    DegeneratePattern {
        corpus: usize,
        max_scan: usize,
    },
}

Errors the grep lane can return.

Variants

InvalidRegex(String)

The pattern is not a valid regular expression.

DegeneratePattern

The pattern yields no usable trigram and the corpus exceeds the scan budget, so it is rejected rather than scanned partially.

Fields

corpus: usize

max_scan: usize

Trait Implementations

impl Clone for GrepError

fn clone(&self) -> GrepError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GrepError

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

Formats the value using the given formatter.

impl Display for GrepError

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

Formats the value using the given formatter.

impl Eq for GrepError

impl Error for GrepError

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 GrepError

fn eq(&self, other: &GrepError) -> 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.
