Enum MatchAtEndBehavior

#[repr(i8)]
pub enum MatchAtEndBehavior {
    WillNeverMatchAtEOD = 0,
    MayMatchAtEOD = 1,
    WillOnlyMatchAtEOD = 2,
}

Available on crate feature compiler only.

Whether this expression can produce matches at end of data (EOD).

In streaming mode, EOD matches are raised during Scratch::flush_eod_sync() or Scratch::flush_eod_sync(), since it is only when flush_eod() is called that the EOD location is known.

Note: trailing \b word boundary assertions may also result in EOD matches as end-of-data can act as a word boundary.

Variants

WillNeverMatchAtEOD = 0

Pattern will never match at EOD.

MayMatchAtEOD = 1

Pattern may match at EOD.

WillOnlyMatchAtEOD = 2

Pattern will only match at EOD.

Trait Implementations

impl Clone for MatchAtEndBehavior

fn clone(&self) -> MatchAtEndBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MatchAtEndBehavior

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

Formats the value using the given formatter.

impl Display for MatchAtEndBehavior

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

Formats the value using the given formatter.

impl Hash for MatchAtEndBehavior

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MatchAtEndBehavior

fn cmp(&self, other: &MatchAtEndBehavior) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MatchAtEndBehavior

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

impl PartialOrd for MatchAtEndBehavior

fn partial_cmp(&self, other: &MatchAtEndBehavior) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
