An instance, pre-instantiation, that is ready to be instantiated.
Structure used to link wasm modules/instances together.
A WebAssembly linear memory.
Error for out of bounds

A compiled WebAssembly module, ready to be instantiated.
Describes the location of an export in a module.
A reference to the abstract nofunc
heap value.
Opaque references to data in the Wasm heap or to host data.
A summary of the amount of resources required to instantiate a particular
Module
or [
Component
][crate::component::Component].
A constructor for externally-created shared memory.
A
Store
is a collection of WebAssembly instances and host-defined state.
Provides limits for a
Store
.
A WebAssembly table
, or an array of values.
A descriptor for a table in a WebAssembly module.
A statically typed WebAssembly function.
Error for an unresolvable import.
Representation of a 128-bit vector type, v128
, for WebAssembly.
Representation of a backtrace of function frames in a WebAssembly module for
where an error happened.
Passed to the argument of
Store::call_hook
to indicate a state transition in
the WebAssembly VM.
An external item to a WebAssembly module, or a list of what can possibly be
exported from a wasm module.
A list of all possible types which can be externally referenced from a
WebAssembly module.
The heap types that can Wasm can have references to.
Represents the module instance allocation strategy to use.
Configure the strategy used for versioning in serializing and deserializing
crate::Module
.
Indicator of whether a global is mutable or not
Possible optimization levels for the Cranelift codegen backend.
Select which profiling technique to support.
A reference.
Possible Compilation strategies for a wasm module.
What to do after returning from a callback when the engine epoch reaches
the deadline for a Store during execution of a function using that store.
Possible runtime values that a WebAssembly module can either consume or
produce.
A list of all possible value types in WebAssembly.
Select how wasm backtrace detailed information is handled.
A trait used to get shared access to a
Store
in Wasmtime.
A trait used to get exclusive mutable access to a
Store
in Wasmtime.
Implementation of an incremental compilation’s key/value cache store.
An object that can take callbacks when the runtime enters or exits hostcalls.
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.
A memory creator. Can be used to provide a memory creator
to wasmtime which supplies host managed memory.
Used by hosts to limit resource consumption of instances.
Used by hosts to limit resource consumption of instances, blocking
asynchronously if necessary.
A stack creator. Can be used to provide a stack creator to wasmtime
which supplies stacks for async support.
A stack memory. This trait provides an interface for raw memory buffers
which are used by wasmtime inside of stacks which wasmtime executes
WebAssembly in for async support. By implementing this trait together
with StackCreator, one can supply wasmtime with custom allocated host
managed stacks.
A trait used for
Func::typed
and with
TypedFunc
to represent the set of
parameters for wasm functions.
A trait implemented for types which can be returned from closures passed to
Func::wrap
and friends.
A trait implemented for types which can be arguments and results for
closures passed to
Func::wrap
as well as parameters to
Func::typed
.
