Enum PeekResult 

pub enum PeekResult<S, E> {
    Found {
        end_slice: usize,
        start: S,
        end: E,
    },
    NotFound,
}

The result of a peeking operation.

A PeekResult contains the result of attempting to match a Peekable against the current position of a Scanner. If the match succeeds, a Found is returned with the length of the end slice, the start of the match, and the end of the match. If the match fails, a NotFound is returned.

Variants

Found

The match was successful.

Fields

end_slice: usize

start: S

end: E

NotFound

The match was unsuccessful.

Trait Implementations

impl<S: Debug, E: Debug> Debug for PeekResult<S, E>

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

Formats the value using the given formatter.

impl<S: PartialEq, E: PartialEq> PartialEq for PeekResult<S, E>

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