pub struct CosmCache<S: Storage + 'static, A: Api + 'static, Q: Querier + 'static> { /* fields omitted */ }

Implementations

impl<S, A, Q> CosmCache<S, A, Q> where
    S: Storage + 'static,
    A: Api + 'static,
    Q: Querier + 'static, [src]

pub unsafe fn new<P: Into<PathBuf>>(
    base_dir: P,
    supported_features: HashSet<String>,
    _cache_size: usize
) -> VmResult<Self>[src]

new stores the data for cache under base_dir

Instance caching is disabled since 0.8.1 and any cache size value will be treated as 0.

Safety

This function is marked unsafe due to FileSystemCache::new, which implicitly assumes the disk contents are correct, and there's no way to ensure the artifacts

pub fn save_wasm(&mut self, wasm: &[u8]) -> VmResult<Checksum>[src]

pub fn load_wasm(&self, checksum: &Checksum) -> VmResult<Vec<u8>>[src]

Retrieves a Wasm blob that was previously stored via save_wasm. When the cache is instantiated with the same base dir, this finds Wasm files on disc across multiple cache instances (i.e. node restarts). This function is public to allow a checksum to Wasm lookup in the blockchain.

If the given ID is not found or the content does not match the hash (=ID), an error is returned.

pub fn get_instance(
    &mut self,
    checksum: &Checksum,
    deps: Extern<S, A, Q>,
    gas_limit: u64
) -> VmResult<Instance<S, A, Q>>[src]

Returns an Instance tied to a previously saved Wasm. Depending on availability, this is either generated from a cached instance, a cached module or Wasm code.
