Struct TypeId

pub struct TypeId(/* private fields */);

Implementations

impl TypeId

pub fn missing(db: &dyn SemanticGroup, diag_added: DiagnosticAdded) -> Self

pub fn format(&self, db: &dyn SemanticGroup) -> String

pub fn check_not_missing(&self, db: &dyn SemanticGroup) -> Maybe<()>

Returns Maybe::Err if the type is TypeLongId::Missing.

pub fn is_missing(&self, db: &dyn SemanticGroup) -> bool

Returns true if the type is TypeLongId::Missing.

pub fn is_unit(&self, db: &dyn SemanticGroup) -> bool

Returns true if the type is ().

pub fn head(&self, db: &dyn SemanticGroup) -> Option<TypeHead>

Returns the TypeHead for a type if available.

pub fn is_fully_concrete(&self, db: &dyn SemanticGroup) -> bool

Returns true if the type does not depend on any generics.

pub fn is_var_free(&self, db: &dyn SemanticGroup) -> bool

Returns true if the type does not contain any inference variables.

pub fn is_phantom(&self, db: &dyn SemanticGroup) -> bool

Returns whether the type is phantom. Type is considered phantom if it has the #[phantom] attribute, or is a tuple or fixed sized array containing it.

Trait Implementations

impl Clone for TypeId

fn clone(&self) -> TypeId

Returns a copy of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<T: ?Sized + Upcast<dyn SemanticGroup + 'static>> DebugWithDb<T> for TypeId

fn fmt(&self, f: &mut Formatter<'_>, db: &T) -> 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 FromIterator<TypeId> for ImplicitPrecedence

fn from_iter<T: IntoIterator<Item = TypeId>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for TypeId

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<'a> Intern<'a, dyn SemanticGroup + 'a, TypeId> for TypeLongId

fn intern(self, db: &(impl Upcast<dyn SemanticGroup + 'a> + ?Sized)) -> TypeId

impl InternKey for TypeId

fn from_intern_id(salsa_id: InternId) -> Self

Create an instance of the intern-key from a u32 value.

fn as_intern_id(&self) -> InternId

Extract the u32 with which the intern-key was created.

impl<'a> LookupIntern<'a, dyn SemanticGroup + 'a, TypeLongId> for TypeId

fn lookup_intern( &self, db: &(impl Upcast<dyn SemanticGroup + 'a> + ?Sized), ) -> TypeLongId

impl PartialEq for TypeId

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