Implementations§

impl TokenKind

pub fn is_trivia(self) -> bool

Returns true if this token is trivia (whitespace or comment).

Trait Implementations§

impl Clone for TokenKind

fn clone(&self) -> TokenKind

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for TokenKind

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

Formats the value using the given formatter. Read more

impl Display for TokenKind

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

Formats the value using the given formatter. Read more

impl FromStr for TokenKind

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<TokenKind, <Self as FromStr>::Err>

Parses a string s to return a value of this type. Read more

impl Hash for TokenKind

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

Feeds this value into the given Hasher. Read more

1.3.0 · Source§

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

Feeds a slice of this type into the given Hasher. Read more

impl PartialEq for TokenKind

fn eq(&self, other: &TokenKind) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

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 TryFrom<&str> for TokenKind

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<TokenKind, <Self as TryFrom<&str>>::Error>

Performs the conversion.
