Trait Implementations

impl Clone for VarId

fn clone(&self) -> VarId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VarId

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

Formats the value using the given formatter.

impl<T> DebugWithDb<T> for VarId

where T: Upcast<dyn DefsGroup> + ?Sized,

fn fmt(&self, f: &mut Formatter<'_>, db: &T) -> Result<(), Error>

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 VarId

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

where __H: Hasher,

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 LanguageElementId for VarId

fn module_file_id(&self, db: &dyn DefsGroup) -> ModuleFileId

fn untyped_stable_ptr(&self, db: &dyn DefsGroup) -> SyntaxStablePtrId

fn stable_location(&self, db: &dyn DefsGroup) -> StableLocation

fn parent_module(&self, db: &dyn DefsGroup) -> ModuleId

fn file_index(&self, db: &dyn DefsGroup) -> FileIndex

impl OptionFrom<VarId> for ParamId

fn option_from(other: VarId) -> Option<ParamId>

impl PartialEq for VarId

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

fn internal_rewrite( &mut self, _value: &mut VarId, ) -> Result<RewriteResult, DiagnosticAdded>

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

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

fn internal_rewrite( &mut self, _value: &mut VarId, ) -> Result<RewriteResult, NoError>

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