This crate provides means to instantiate and execute wasm modules.
|
|
|
|
It works even when the user of this library executes from
|
|
inside the wasm VM. In this case the same VM is used for execution
|
|
of both the sandbox owner and the sandboxed module, without compromising security
|
|
and without the performance penalty of full wasm emulation inside wasm.
|
|
|
|
This is achieved by using bindings to the wasm VM, which are published by the host API.
|
|
This API is thin and consists of only a handful functions. It contains functions for instantiating
|
|
modules and executing them, but doesn't contain functions for inspecting the module
|
|
structure. The user of this library is supposed to read the wasm module.
|
|
|
|
When this crate is used in the `std` environment all these functions are implemented by directly
|
|
calling the wasm VM.
|
|
|
|
Examples of possible use-cases for this library are not limited to the following:
|
|
|
|
- implementing smart-contract runtimes that use wasm for contract code
|
|
- executing a wasm substrate runtime inside of a wasm parachain
