Struct PatternVariable

pub struct PatternVariable {
    pub name: SmolStr,
    pub var: LocalVariable,
    pub stable_ptr: PatternPtr,
}

Trait Implementations

impl Clone for PatternVariable

fn clone(&self) -> PatternVariable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PatternVariable

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

Formats the value using the given formatter.

impl DebugWithDb<ExprFormatter<'_>> for PatternVariable

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

fn debug<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

fn into_debug<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

impl Hash for PatternVariable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PatternVariable

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

impl<T: SemanticRewriter<LocalVariable, Error>, Error> SemanticObject<T, Error> for PatternVariable

fn default_rewrite(&mut self, rewriter: &mut T) -> Result<RewriteResult, Error>

impl<'a> SemanticRewriter<PatternVariable, NoError> for Inference<'a>

fn internal_rewrite( &mut self, value: &mut PatternVariable, ) -> Result<RewriteResult, NoError>

fn rewrite(&mut self, value: T) -> Result<T, Error>
