Implementations

impl PluginModuleCacheInner

pub fn get_fs_cache_root(&self) -> Option<String>

pub fn contains(&self, key: &str) -> bool

Check if the cache contains bytes for the corresponding key.

pub fn insert_raw_bytes(&mut self, key: String, value: Vec<u8>)

Insert raw plugin module bytes into cache does not have compiled wasmer::Module. The bytes stored in this type of cache will return RawPluginModuleBytes. It is strongly recommend to avoid using this type of cache as much as possible, since module compilation time for the wasm is noticeably expensive and caching raw bytes only cuts off the reading time for the plugin module.

pub fn insert_compiled_module_bytes( &mut self, key: String, value: (Store, Module), )

Insert already compiled wasmer::Module into cache. The module stored in this cache will return CompiledPluginModuleBytes, which costs near-zero time when calling its compile_module method as it clones precompiled module directly.

In genearl it is recommended to use either using filesystemcache store_bytes_from_path which internally calls this or directly call this to store compiled module bytes. CompiledModuleBytes provides way to create it via RawModuleBytes, so there’s no practical reason to store raw bytes most cases.

pub fn store_bytes_from_path( &mut self, binary_path: &Path, key: &str, ) -> Result<(), Error>

Store plugin module bytes into the cache, from actual filesystem.

pub fn get(&self, key: &str) -> Option<Box<dyn PluginModuleBytes>>

Returns a PluingModuleBytes can be compiled into a wasmer::Module. Depends on the cache availability, it may return a raw bytes or a serialized bytes.
