Struct wasm_runtime_layer::backend::Imports

pub struct Imports<E: WasmEngine> { /* private fields */ }

All of the import data used when instantiating.

Implementations

impl<E: WasmEngine> Imports<E>

pub fn new() -> Self

Create a new Imports.

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

Gets an export given a module and a name

pub fn exists(&self, module: &str, name: &str) -> bool

Returns if an export exist for a given module and name.

pub fn contains_namespace(&self, name: &str) -> bool

Returns true if the Imports contains namespace with the provided name.

pub fn register_namespace( &mut self, ns: &str, contents: impl IntoIterator<Item = (String, Extern<E>)> )

Register a list of externs into a namespace.

pub fn define(&mut self, ns: &str, name: &str, val: impl Into<Extern<E>>)

Add a single import with a namespace ns and name name.

pub fn iter(&self) -> ImportsIterator<'_, E>

Iterates through all the imports in this structure

Trait Implementations

impl<E: Clone + WasmEngine> Clone for Imports<E>

fn clone(&self) -> Imports<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: WasmEngine> Debug for Imports<E>

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

Formats the value using the given formatter.

impl<E: WasmEngine> Default for Imports<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: WasmEngine> Extend<((String, String), Extern<E>)> for Imports<E>

fn extend<T: IntoIterator<Item = ((String, String), Extern<E>)>>( &mut self, iter: T )

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl<E: WasmEngine> IntoIterator for &Imports<E>

type IntoIter = IntoIter<(String, String), Extern<E>>

Which kind of iterator are we turning this into?

type Item = ((String, String), Extern<E>)

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
