[−][src]Crate wasi_common_lucet

Modules

fs	A very experimental module modeled providing a high-level and safe filesystem interface, modeled after `std::fs`, implemented on top of WASI functions.
hostcalls
old
wasi	Types and constants shared between 32-bit and 64-bit wasi. Types involving pointer or `usize`-sized data are excluded here, so this file only contains fixed-size types, so it's host/target independent.
wasi32	Types and constants specific to 32-bit wasi. These are similar to the types in the `host` module, but pointers and `usize` values are replaced with `u32`-sized types.

Terminate an instance from within a hostcall, returning an optional value as an error.

Vmctx	An opaque handle to a running instance's context.
WasiCtx
WasiCtxBuilder	A builder allowing customizable construction of `WasiCtx` instances.
lucet_vmctx	Marker type for the `vmctx` pointer argument.

This attribute generates a Lucet hostcall from a standalone Rust function that takes a &mut Vmctx as its first argument.
