Implementations

impl Keyword

pub fn as_binop(self) -> Option<BinOp>

Gets the keyword as a binary operation, if this keyword is the in keyword.

pub fn as_str(self) -> &'static str

Gets the keyword as a string.

Trait Implementations

impl Clone for Keyword

fn clone(&self) -> Keyword

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Keyword

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

Formats the value using the given formatter.

impl Display for Keyword

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

Formats the value using the given formatter.

impl From<Keyword> for TokenKind

fn from(kw: Keyword) -> Self

Converts to this type from the input type.

impl FromStr for Keyword

type Err = KeywordError

The associated error which can be returned from parsing.

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

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

impl PartialEq<Keyword> for Punctuator

fn eq(&self, _other: &Keyword) -> 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 PartialEq<Punctuator> for Keyword

fn eq(&self, _other: &Punctuator) -> 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 PartialEq for Keyword

fn eq(&self, other: &Keyword) -> 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 TryInto<BinOp> for Keyword

type Error = String

The type returned in the event of a conversion error.

fn try_into(self) -> Result<BinOp, Self::Error>

Performs the conversion.

impl Copy for Keyword

impl StructuralPartialEq for Keyword
