Struct wasmer_cache::FileSystemCache
source · pub struct FileSystemCache { /* private fields */ }
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::{DeserializeError, SerializeError};
use wasmer_cache::{Cache, FileSystemCache, Hash};
fn store_module(module: &Module, bytes: &[u8]) -> Result<(), SerializeError> {
// Create a new file system cache.
let mut fs_cache = FileSystemCache::new("some/directory/goes/here")?;
// Compute a key for a given WebAssembly binary
let key = Hash::generate(bytes);
// Store a module into the cache given a key
fs_cache.store(key, module)?;
Ok(())
}
Implementations
sourceimpl FileSystemCache
impl FileSystemCache
sourcepub fn new<P: Into<PathBuf>>(path: P) -> Result<Self>
pub fn new<P: Into<PathBuf>>(path: P) -> Result<Self>
Construct a new FileSystemCache
around the specified directory.
sourcepub fn set_cache_extension(&mut self, ext: Option<impl ToString>)
pub fn set_cache_extension(&mut self, ext: Option<impl ToString>)
Set the extension for this cached file.
This is needed for loading native files from Windows, as otherwise
loading the library will fail (it requires a .dll
extension)
