A crate that provides means of executing/dispatching calls into the runtime.
There are a few responsibilities of this crate at the moment:
- It provides an implementation of a common entrypoint for calling into the runtime, both wasm and compiled.
- It defines the environment for the wasm execution, namely the host functions that are to be provided into the wasm runtime module.
- It also provides the required infrastructure for executing the current wasm runtime (specified
by the current value of
:codein the provided externalities), i.e. interfacing with wasm engine used, instance cache.
Rust executor possible errors.
This module implements sandboxing support in the runtime.
CodeExecutor implementation that uses a delegate to determine wasm code equivalence
and dispatch to native code when possible, falling back on
WasmExecutor when not.
This should not be thought of as classic Semver (major/minor/tiny).
This triplet have different semantics and mis-interpretation could cause problems.
In particular: bug fixes should result in an increment of
spec_version and possibly
authoring_version, absolutely not
impl_version since they change the semantics of the
An abstraction over Wasm code executor. Supports selecting execution backend and manages runtime cache.
Specification of different methods of executing the runtime Wasm code.
Trait that allows zero-copy read/write of value-references to/from slices in LE format.
Delegate for dispatching a CodeExecutor call.
Extracts the runtime version of a given runtime code.
