The different kinds of types recognized by the compiler
Variants
Slice(P<Ty>)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A variable-length slice ([T]
)
Array(P<Ty>, AnonConst)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A fixed length array ([T; n]
)
Ptr(MutTy)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A raw pointer (*const T
or *mut T
)
Rptr(Option<Lifetime>, MutTy)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A reference (&'a T
or &'a mut T
)
BareFn(P<BareFnTy>)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A bare function (e.g. fn(usize) -> bool
)
Never
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
The never type (!
)
Tup(Vec<P<Ty>>)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A tuple ((A, B, C, D,...)
)
Path(Option<QSelf>, Path)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A path (module::module::...::Type
), optionally
"qualified", e.g. <Vec<T> as SomeTrait>::SomeType
.
Type parameters are stored in the Path itself
TraitObject(GenericBounds, TraitObjectSyntax)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
A trait object type Bound1 + Bound2 + Bound3
where Bound
is a trait or a lifetime.
ImplTrait(NodeId, GenericBounds)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
An impl Bound1 + Bound2 + Bound3
type
where Bound
is a trait or a lifetime.
The NodeId
exists to prevent lowering from having to
generate NodeId
s on the fly, which would complicate
the generation of existential type
items significantly
Paren(P<Ty>)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
No-op; kept solely so that we can pretty-print faithfully
Typeof(AnonConst)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
Unused for now
Infer
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
TyKind::Infer means the type should be inferred instead of it having been specified. This can appear anywhere in a type.
ImplicitSelf
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
Inferred type of a self
or &self
argument in a method.
Mac(Mac)
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
Err
🔬 This is a nightly-only experimental API. (rustc_private

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml

Placeholder for a kind that has failed to be defined.

is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
