Enum TypeExpr 

pub enum TypeExpr {
    Primitive(Span<Type>),
    Ptr(PointerType),
    Array(ArrayType),
    Struct(StructType),
    Ref(Span<Arc<Path>>),
}

A syntax-level type expression (i.e. primitive type, reference to nominal type, etc.)

Variants

Primitive(Span<Type>)

A primitive integral type, e.g. i1, u16

Ptr(PointerType)

A pointer type expression, e.g. *u8

Array(ArrayType)

An array type expression, e.g. [u8; 32]

Struct(StructType)

A struct type expression, e.g. struct { a: u32 }

Ref(Span<Arc<Path>>)

A reference to a type aliased by name, e.g. Foo

Implementations

impl TypeExpr

pub fn set_name(&mut self, name: Ident)

Set the name associated with this type expression, if applicable.

Currently this just sets the name of struct types, but if we add other types with names in the future, we can support them here.

pub fn references(&self) -> Vec<Span<Arc<Path>>>

Get any references to other types present in this expression

pub fn resolve_type<E, R>(&self, resolver: &mut R) -> Result<Option<Type>, E>

where R: TypeResolver<E> + ?Sized,

Resolve this type expression to a concrete type, using resolver

Trait Implementations

impl Clone for TypeExpr

fn clone(&self) -> TypeExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeExpr

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

Formats the value using the given formatter.

impl From<Type> for TypeExpr

fn from(ty: Type) -> TypeExpr

Converts to this type from the input type.

impl Hash for TypeExpr

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 PartialEq for TypeExpr

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

impl PrettyPrint for TypeExpr

fn render(&self) -> Document

The core of the [PrettyPrint] functionality.

fn to_pretty_string(&self) -> String

Produce a String containing the results of pretty-printing this object.

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

Pretty-print this object to the given core::fmt::Formatter.

impl Spanned for TypeExpr

fn span(&self) -> SourceSpan

impl Eq for TypeExpr

impl StructuralPartialEq for TypeExpr
