Trait Implementations

impl<'db> Clone for VarId<'db>

fn clone(&self) -> VarId<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for VarId<'db>

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

Formats the value using the given formatter.

impl<'db> DebugWithDb<'db> for VarId<'_>

type Db = dyn Database

fn fmt( &self, f: &mut Formatter<'_>, db: &'db (dyn Database + 'static), ) -> Result<(), Error>

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

where Self: Sized + 'me,

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

where Self: Sized + 'me,

impl<'db> Hash for VarId<'db>

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<'db> LanguageElementId<'db> for VarId<'db>

fn module_id(&self, db: &'db (dyn Database + 'static)) -> ModuleId<'db>

fn untyped_stable_ptr( &self, db: &'db (dyn Database + 'static), ) -> SyntaxStablePtrId<'db>

fn stable_location( &self, db: &'db (dyn Database + 'static), ) -> StableLocation<'db>

fn parent_module(&self, db: &'db (dyn Database + 'static)) -> ModuleId<'db>

impl<'db> OptionFrom<VarId<'db>> for ParamId<'db>

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

impl<'db> PartialEq for VarId<'db>

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

Returns
