Enum wasm_encoder::CanonicalOption

pub enum CanonicalOption {
    UTF8,
    UTF16,
    CompactUTF16,
    Memory(u32),
    Realloc(u32),
    PostReturn(u32),
}

Represents options for canonical function definitions.

Variants

UTF8

The string types in the function signature are UTF-8 encoded.

UTF16

The string types in the function signature are UTF-16 encoded.

CompactUTF16

The string types in the function signature are compact UTF-16 encoded.

Memory(u32)

The memory to use if the lifting or lowering of a function requires memory access.

The value is an index to a core memory.

Realloc(u32)

The realloc function to use if the lifting or lowering of a function requires memory allocation.

The value is an index to a core function of type (func (param i32 i32 i32 i32) (result i32)).

PostReturn(u32)

The post-return function to use if the lifting of a function requires cleanup after the function returns.

Trait Implementations

impl Clone for CanonicalOption

fn clone(&self) -> CanonicalOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CanonicalOption

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

Formats the value using the given formatter.

impl Encode for CanonicalOption

fn encode(&self, sink: &mut Vec<u8>)

Encode the type into the given byte sink.

impl From<CanonicalOption> for CanonicalOption

fn from(opt: CanonicalOption) -> Self

Converts to this type from the input type.

impl PartialEq for CanonicalOption

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