Enum PeekResult

pub enum PeekResult {
    Matches(Vec<Match>),
    MatchesReachedEnd(Vec<Match>),
    MatchesReachedModeSwitch((Vec<Match>, usize)),
    NotFound,
}

The result of a peek operation.

Variants

Matches(Vec<Match>)

The peek operation found n matches.

MatchesReachedEnd(Vec<Match>)

The peek operation found less than n matches because the end of the haystack was reached.

MatchesReachedModeSwitch((Vec<Match>, usize))

The peek operation found less than n matches because the last token type would have triggered a mode switch. The matches are returned along with the index of the new mode that would be switched to on the last match.

NotFound

The peek operation found no matches.

Trait Implementations

impl Debug for PeekResult

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

Formats the value using the given formatter.

impl PartialEq for PeekResult

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