where for<'db> TypeLongId<'db>: Debug,

Default debug formatting for this struct (may be useful if you define your own Debug impl)

impl<'db> TypeId<'db>

pub fn from_intern_id(intern_id: Id) -> Self

pub fn as_intern_id(self) -> Id

impl<'db> TypeId<'db>

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

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

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

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

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

Returns true if the type is TypeLongId::Missing.

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

Returns true if the type is ().

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

Returns the TypeHead for a type if available.

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

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

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

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

pub fn is_phantom(&self, db: &dyn Database) -> 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.

pub fn short_name(&self, db: &dyn Database) -> String

Short name of the type argument.

Trait Implementations

impl<'db> HasJar for TypeId<'db>

const KIND: JarKind = zalsa_::JarKind::Struct

The [JarKind] for Self::Jar.
