Struct wasm::execution::value::ExternAddr

pub struct ExternAddr {
    pub addr: Option<usize>,
}

Represents the address of an external reference in the interpreter.

External references are managed at the interpreter level and are not part of the WebAssembly module itself. They are typically used to refer to host functions or objects that interact with the module.

Internally, ExternAddr corresponds to an index in a linear vector, enabling dynamic storage and retrieval of external values.

Fields

addr: Option<usize>

Implementations

impl ExternAddr

pub fn new(addr: Option<usize>) -> Self

pub fn null() -> Self

Trait Implementations

impl Clone for ExternAddr

fn clone(&self) -> ExternAddr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExternAddr

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

Formats the value using the given formatter.

impl Default for ExternAddr

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ExternAddr

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