Struct wasmer_runtime_fl::cache::FileSystemCache [−][src]
pub struct FileSystemCache { /* fields omitted */ }
Expand description
Representation of a directory that contains compiled wasm artifacts.
The FileSystemCache
type implements the Cache
trait, which allows it to be used
generically when some sort of cache is required.
Usage:
use wasmer_runtime::cache::{Cache, FileSystemCache, WasmHash}; fn store_module(module: Module) -> Result<Module, CacheError> { // Create a new file system cache. // This is unsafe because we can't ensure that the artifact wasn't // corrupted or tampered with. let mut fs_cache = unsafe { FileSystemCache::new("some/directory/goes/here")? }; // Compute a key for a given WebAssembly binary let key = WasmHash::generate(&[]); // Store a module into the cache given a key fs_cache.store(key, module.clone())?; Ok(module) }
Implementations
Construct a new FileSystemCache
around the specified directory.
The contents of the cache are stored in sub-versioned directories.
Note:
This method is unsafe because there’s no way to ensure the artifacts stored in this cache haven’t been corrupted or tampered with.
