Implementations§

impl Expression

pub fn location(&self) -> &Location

Get the location of this expression

pub fn is_constant(&self) -> bool

Check if this expression is a constant literal

pub fn is_variable(&self) -> bool

Check if this expression is a simple variable reference

Trait Implementations§

impl Clone for Expression

fn clone(&self) -> Expression

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for Expression

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

Formats the value using the given formatter. Read more

impl PartialEq for Expression

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