Implementations§

impl JsToken

pub fn can_end_statement(&self) -> bool

Whether this token can end a statement (for ASI purposes)

pub fn is_keyword(&self) -> bool

Whether this token is a keyword

Trait Implementations§

impl Clone for JsToken

fn clone(&self) -> JsToken

Returns a duplicate of the value. Read more

1.0.0§

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

Performs copy-assignment from source. Read more

impl Debug for JsToken

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

Formats the value using the given formatter. Read more

impl PartialEq for JsToken

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

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

1.0.0§

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 StructuralPartialEq for JsToken

Auto Trait Implementations§

impl Send for JsToken

impl Sync for JsToken

impl Unpin for JsToken

impl UnwindSafe for JsToken
