Struct wasm_component_layer::VariantType

pub struct VariantType { /* private fields */ }

Describes a type has multiple possible states. Each state may optionally have a type associated with it.

Implementations

impl VariantType

pub fn new( name: Option<TypeIdentifier>, cases: impl IntoIterator<Item = VariantCase> ) -> Result<Self>

Creates a new type for the given set of variant cases. Each case must have a unique name.

pub fn cases(&self) -> &[VariantCase]

Gets all of the cases for this variant.

pub fn name(&self) -> Option<&TypeIdentifier>

Gets the name of this type, if any.

Trait Implementations

impl Clone for VariantType

fn clone(&self) -> VariantType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VariantType

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

Formats the value using the given formatter.

impl Hash for VariantType

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 PartialEq for VariantType

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