Implementations

impl Keyword

pub const fn as_binary_op(self) -> Option<BinaryOp>

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

pub const fn as_str(self) -> (&'static str, &'static [u16])

Gets the keyword as a tuple of strings.

pub const fn to_sym(self) -> Sym

Converts the keyword to a symbol in the given interner.

Trait Implementations

impl Clone for Keyword

fn clone(&self) -> Keyword

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Keyword

fn deserialize<__D>( __deserializer: __D, ) -> Result<Keyword, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Keyword

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

Formats the value using the given formatter.

impl FromStr for Keyword

type Err = KeywordError

The associated error which can be returned from parsing.

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

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

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 Serialize for Keyword

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Keyword> for BinaryOp

type Error = String

The type returned in the event of a conversion error.

fn try_from( value: Keyword, ) -> Result<BinaryOp, <BinaryOp as TryFrom<Keyword>>::Error>

Performs the conversion.

impl Copy for Keyword

impl Eq for Keyword

impl StructuralPartialEq for Keyword
