Struct TokenRef 

pub struct TokenRef<'a> {
    pub text: &'a str,
    pub start: usize,
    pub end: usize,
}

A borrowed token with character offsets into the source text.

start and end are character offsets (Unicode scalar values), not byte offsets. To recover the substring from the original text, use text.chars().skip(start).take(end - start).collect::<String>().

Fields

text: &'a str

The token text (borrowed slice).

start: usize

Character offset where the token starts (inclusive).

end: usize

Character offset where the token ends (exclusive).

Trait Implementations

impl<'a> Clone for TokenRef<'a>

fn clone(&self) -> TokenRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TokenRef<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for TokenRef<'a>

fn eq(&self, other: &TokenRef<'a>) -> 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.
