Implementations

impl Expr

pub fn meta(&self) -> Option<&Meta>

Returns metadata when the expression carries explicit Draxl metadata.

pub fn meta_mut(&mut self) -> Option<&mut Meta>

Returns mutable metadata when the expression carries explicit Draxl metadata.

pub fn clear_spans(&mut self)

Removes span data from the expression in place.

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl PartialEq for Expr

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