Implementations

impl TypeLongId

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

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

Returns the TypeHead for a type if available.

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 an other attribute declared by a plugin as defining a phantom type), or is a tuple or fixed sized array containing it.

Trait Implementations

impl Clone for TypeLongId

fn clone(&self) -> TypeLongId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeLongId

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

Formats the value using the given formatter.

impl DebugWithDb<dyn SemanticGroup> for TypeLongId

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

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

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

impl OptionFrom<TypeLongId> for ConcreteTypeId

fn option_from(other: TypeLongId) -> Option<Self>

impl PartialEq for TypeLongId

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