Struct cranelift_wasm::wasmparser::SubType

pub struct SubType {
    pub is_final: bool,
    pub supertype_idx: Option<PackedIndex>,
    pub composite_type: CompositeType,
}

Represents a subtype of possible other types in a WebAssembly module.

Fields

is_final: bool

Is the subtype final.

supertype_idx: Option<PackedIndex>

The list of supertype indexes. As of GC MVP, there can be at most one supertype.

composite_type: CompositeType

The composite type of the subtype.

Implementations

impl SubType

pub fn unwrap_array(&self) -> &ArrayType

Unwrap an ArrayType or panic.

Does not check finality or whether there is a supertype.

pub fn unwrap_func(&self) -> &FuncType

Unwrap an FuncType or panic.

Does not check finality or whether there is a supertype.

pub fn unwrap_struct(&self) -> &StructType

Unwrap an StructType or panic.

Does not check finality or whether there is a supertype.

Trait Implementations

impl Clone for SubType

fn clone(&self) -> SubType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SubType

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

Formats the value using the given formatter.

impl Display for SubType

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

Formats the value using the given formatter.

impl<'a> FromReader<'a> for SubType

fn from_reader( reader: &mut BinaryReader<'a> ) -> Result<SubType, BinaryReaderError>

Attempts to read Self from the provided binary reader, returning an error if it is unable to do so.

impl Hash for SubType

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 SubType

fn eq(&self, other: &SubType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeData for SubType

type Id = CoreTypeId

The identifier for this type data.

impl Eq for SubType

impl StructuralPartialEq for SubType
