* Add a `wasmtime::Linker` type This commit adds a new type to the `wasmtime` crate, a `Linker`. This linker is intended to vastly simplify calling `Instance::new` by easily performing name resolution and incrementally defining state over time. The goal here is to start down a path of making linking wasm modules in `wasmtime` a first-class and ergonomic operation. This is highly likely to evolve over time and get tweaked through releases as we iterate towards a design well-suited for `wasmtime`, but this is intended to at least be the initial foundation for such functionality. This commit additionally also adds a C API for the linker and switches the existing linking examples to using this linker in both Rust and C. One piece of future work I'd like to tackle next is to integrate WASI into the `wasmtime` crate in a more first-class manner. This [`Linker`] type provides a great location to hook into the instantiation process to easily instantiate modules with WASI imports. That's a relatively large refactoring for now though and I figured it'd be best left for a different time. Closes #727
Examples of the wasmtime API
This directory contains a number of examples of using the wasmtime API from
different languages. Currently examples are all in Rust and C using the
wasmtime crate or the wasmtime embedding API.
Each example is available in both C and in Rust. Examples are accompanied with a
*.wat file which is the wasm input, or a Rust project in a wasm folder which
is the source code for the original wasm file.
Rust examples can be executed with cargo run --example $name, and C examples
need to be compiled using your system compiler and appropriate header files.
For more information see the examples themselves!
