Re-exports

• pub use frame_info::FRAME_INFO;
• pub use frame_info::FRAME_INFO;

Structs

• EngineId
  A unique identifier for an Engine.
• ExportFunction
  A function export value with an extra function pointer to initialize host environments.
• ExportFunctionMetadata
  Extra metadata about ExportFunctions.
• FRAME_INFO
  This is a global cache of backtrace frame information for all active
• FrameInfo
  Description of a frame in a backtrace for a RuntimeError::trace.
• FunctionExtent
  Represents a continuous region of executable memory starting with a function entry point.
• GlobalFrameInfoRegistration
  An RAII structure used to unregister a module’s frame information when the module is destroyed.
• MetadataHeader
  Metadata header which holds an ABI version and the length of the remaining metadata.
• NamedResolverChain
  A Resolver that links two resolvers together in a chain.
• NullResolver
  Resolver implementation that always resolves to None. Equivalent to ().
• RuntimeError
  A struct representing an aborted instruction execution, with a message indicating the cause.

Enums

• DeserializeError
  The Deserialize error can occur when loading a compiled Module from a binary.
• Export
  The value of an export passed from one instance to another.
• ImportError
  An ImportError.
• InstantiationError
  An error while instantiating a module.
• LinkError
  The WebAssembly.LinkError object indicates an error during module instantiation (besides traps from the start function).

Traits

• Artifact

• ArtifactCreate
  An Artifact is the product that the Engine implementation produce and use.
• ChainableNamedResolver
  A trait for chaining resolvers together.
• Engine
  A unimplemented Wasmer Engine.
• NamedResolver
  Import resolver connects imports with available exported values.
• Resolver
  Import resolver connects imports with available exported values.
• Tunables

Functions

• register_frame_info
  Registers a new compiled module’s frame information.
• resolve_imports
  This function allows to match all imports of a ModuleInfo with concrete definitions provided by a Resolver.
