Struct wasmi::Linker

pub struct Linker<T> { /* private fields */ }

A linker used to define module imports and instantiate module instances.

Implementations

impl<T> Linker<T>

pub fn new() -> Self

Creates a new linker.

pub fn define(
    &mut self,
    module: &str,
    name: &str,
    item: impl Into<Extern>
) -> Result<&mut Self, LinkerError>

Define a new item in this Linker.

Errors

If there already is a definition under the same name for this Linker.

pub fn resolve(&self, module: &str, name: Option<&str>) -> Option<Extern>

Looks up a previously defined extern value in this Linker.

Returns None if this name was not previously defined in this Linker.

pub fn instantiate<'a>(
    &mut self,
    context: impl AsContextMut,
    module: &'a Module
) -> Result<InstancePre<'a>, Error>

Instantiates the given Module using the definitions in the Linker.

Errors

• If the linker does not define imports of the instantiated Module.
• If any imported item does not satisfy its type requirements.
