Module holochain_wasmer_host::module

Structs

• DeserializedModuleCache
  Caches deserialized wasm modules. Deserialization of cached modules from the cache to create callable instances is slow. Therefore modules are cached in memory after deserialization.
• InstanceWithStore
• ModuleCache
• ModuleWithStore
• SerializedModuleCache
  Cache for serialized modules. These are fully compiled wasm modules that are then serialized by wasmer and can be cached. A serialized wasm module must still be deserialized before it can be used to build instances. The deserialization process is far faster than compiling and much slower than instance building.

Constants

• WASM_METERING_LIMIT
  one hundred giga ops

Traits

• PlruCache
  Higher level trait over the plru cache to make it a bit easier to interact with consistently. Default implementations for key functions are provided. Notably handles keeping the mapping between cache keys and items, and the plru tracking including touching and evicting.

Functions

• build_ios_module
  Take WASM binary and prepare a wasmer Module suitable for iOS
• get_ios_module_from_file
  Deserialize a previously compiled module for iOS from a file.
• make_compiler_engine
  Generate an engine with a wasm compiler and Metering (use limits) in place.
• make_ios_runtime_engine
  Generate a runtime Engine without compiler suitable for iOS. Useful for re-building an iOS Module from a preserialized WASM Module.
• wasmer_ios_target
  Configuration of a Target for wasmer for iOS

Type Aliases

• CacheKey
  We expect cache keys to be produced via hashing so 32 bytes is enough for all purposes.
• PlruKeyMap
  Plru uses a usize to track “recently used” so we need a map between 32 byte cache keys and the bits used to evict things from the cache.
• SerializedModule
  Modules serialize to a vec of bytes as per wasmer.
