Implementations§

Source§

impl Operator

Source

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

Returns the literal string representation of the operator.

Source

pub const fn is_clause_delimiter(self) -> bool

Determines if this token can be a delimiter of a clause.

This function returns true for CloseParen and SemicolonSemicolon, and false for others.
