Struct wasmtime_environ::component::TypeVariant

pub struct TypeVariant {
    pub cases: IndexMap<String, Option<InterfaceType>>,
    pub abi: CanonicalAbiInfo,
    pub info: VariantInfo,
}

Shape of a “variant” type in interface types.

Variants are close to Rust enum declarations where a value is one of many cases and each case has a unique name and an optional payload associated with it.

Fields

cases: IndexMap<String, Option<InterfaceType>>

The list of cases that this variant can take.

abi: CanonicalAbiInfo

Byte information about this type in the canonical ABI.

info: VariantInfo

Byte information about this variant type.

Trait Implementations

impl Clone for TypeVariant

fn clone(&self) -> TypeVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeVariant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TypeVariant

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TypeVariant

fn hash<H: Hasher>(&self, h: &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 TypeVariant

fn eq(&self, other: &TypeVariant) -> 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 Serialize for TypeVariant

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TypeVariant
