Enum TokenContext

#[repr(u8)]
pub enum TokenContext {
    BraceStmt,
    BraceExpr,
    TplQuasi,
    ParenStmt {
        is_for_loop: bool,
    },
    ParenExpr,
    Tpl {
        start: BytePos,
    },
    FnExpr,
    ClassExpr,
    JSXOpeningTag,
    JSXClosingTag,
    JSXExpr,
}

The algorithm used to determine whether a regexp can appear at a given point in the program is loosely based on sweet.js’ approach. See https://github.com/mozilla/sweet.js/wiki/design

Implementations

impl TokenContext

pub fn is_expr(&self) -> bool

pub fn preserve_space(&self) -> bool

Trait Implementations

impl Clone for TokenContext

fn clone(&self) -> TokenContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenContext

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

Formats the value using the given formatter.

impl PartialEq for TokenContext

fn eq(&self, other: &TokenContext) -> 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.
