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 the following operators:

  • CloseParen ())
  • SemicolonAnd (;&)
  • SemicolonSemicolon (;;)
  • SemicolonSemicolonAnd (;;&)
  • SemicolonBar (;|)

Source§

impl PartialEq for Operator

Source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
Source§

impl TryFrom<Operator> for AndOr

Source§

type Error = TryFromOperatorError

Source§

impl TryFrom<Operator> for CaseContinuation

Source§

fn try_from(op: Operator) -> Result<CaseContinuation, TryFromOperatorError>
