Struct wasmtime_environ::component::VariantInfo

pub struct VariantInfo {
    pub size: DiscriminantSize,
    pub payload_offset32: u32,
    pub payload_offset64: u32,
}

ABI information about the representation of a variant.

Fields

size: DiscriminantSize

The size of the discriminant used.

payload_offset32: u32

The offset of the payload from the start of the variant in 32-bit memories.

payload_offset64: u32

The offset of the payload from the start of the variant in 64-bit memories.

Implementations

impl VariantInfo

pub fn new<'a, I>(cases: I) -> (VariantInfo, CanonicalAbiInfo)

where I: IntoIterator<Item = Option<&'a CanonicalAbiInfo>>, I::IntoIter: ExactSizeIterator,

Returns the abi information for a variant represented by the specified cases.

pub const fn new_static(cases: &[Option<CanonicalAbiInfo>]) -> VariantInfo

TODO

Trait Implementations

impl Clone for VariantInfo

fn clone(&self) -> VariantInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VariantInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VariantInfo

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for VariantInfo

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 VariantInfo

fn eq(&self, other: &VariantInfo) -> 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 VariantInfo

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 VariantInfo
