wasmer-cache

The wasmer-cache crate allows to cache WebAssembly modules (of kind wasmer::Module) in your system, so that next uses of the module does imply a compilation time.

Usage

The Cache trait represents a generic cache for storing and loading compiled WebAssembly modules. The FileSystemCache type implements Cache to store cache on the file system.

```rust use wasmer::{DeserializeError, Module, SerializeError}; use wasmer_cache::{Cache, FileSystemCache, Hash};

fn storemodule(module: &Module, bytes: &[u8]) -> Result<(), SerializeError> { // Create a new file system cache. let mut fscache = FileSystemCache::new("some/directory/goes/here")?;

// Compute a key for a given WebAssembly binary
let hash = Hash::generate(bytes);

// Store a module into the cache given a key
fs_cache.store(hash, module.clone())?;

Ok(())

} ```
