Constants

• DEFAULT_INSTANCE_LIMIT
  Value returned by ResourceLimiter::instances default method
• DEFAULT_MEMORY_LIMIT
  Value returned by ResourceLimiter::memories default method
• DEFAULT_TABLE_LIMIT

Traits

• AsContext
  A trait used to get shared access to a Store in Wasmtime.
• AsContextMut
  A trait used to get exclusive mutable access to a Store in Wasmtime.
• CacheStore
  Implementation of an incremental compilation’s key/value cache store.
• CallHookHandler
  An object that can take callbacks when the runtime enters or exits hostcalls.
• IntoFunc
  Internal trait implemented for all arguments that can be passed to Func::wrap and Linker::func_wrap.
• LinearMemory
  A linear memory. This trait provides an interface for raw memory buffers which are used by wasmtime, e.g. inside [‘Memory’]. Such buffers are in principle not thread safe. By implementing this trait together with MemoryCreator, one can supply wasmtime with custom allocated host managed memory.
• MemoryCreator
  A memory creator. Can be used to provide a memory creator to wasmtime which supplies host managed memory.
• ResourceLimiter
  Used by hosts to limit resource consumption of instances.
• ResourceLimiterAsync
  Used by hosts to limit resource consumption of instances, blocking asynchronously if necessary.
• WasmParams
  A trait used for Func::typed and with TypedFunc to represent the set of parameters for wasm functions.
• WasmResults
  A trait used for Func::typed and with TypedFunc to represent the set of results for wasm functions.
• WasmRet
  A trait implemented for types which can be returned from closures passed to Func::wrap and friends.
• WasmTy
  A trait implemented for types which can be arguments and results for closures passed to Func::wrap as well as parameters to Func::typed.

Type Definitions

• Result
  Result<T, Error>

Unions

• ValRaw
  A “raw” and unsafe representation of a WebAssembly value.
