Crate wasmtime_runtime[−][src]
Expand description
Runtime library support for Wasmtime.
Modules
Runtime library calls.
Structs
A function export value.
A global export value.
A memory export value.
A table export value.
Registeration for JIT image
Resolved import pointers.
Represents a request for a new runtime instance.
A handle holding an Instance
of a WebAssembly module.
Represents the limits placed on instances by the pooling instance allocator.
An link error while instantiating a module.
A simple struct consisting of a page-aligned pointer to page-aligned and initially-zeroed memory and a length.
Represents the limits placed on a module for compiling with the pooling instance allocator.
Represents the on-demand instance allocator.
Implements the pooling instance allocator.
Opaque state used to help control TLS state across stack switches for async support.
The VM caller-checked “anyfunc” record, for caller-side signature checking. It consists of the actual function pointer and a signature id to be checked by the caller.
The VM “context”, which is pointed to by the vmctx
arg in Cranelift.
This has information about globals, memories, tables, and other runtime
state associated with the current instance.
An external reference to some opaque data.
A table that over-approximizes the set of VMExternRef
s that any Wasm
activation on this thread is currently using.
A placeholder byte-sized type which is just used to provide some amount of type safety when dealing with pointers to JIT-compiled function bodies. Note that it’s deliberately not Copy, as we shouldn’t be carelessly copying function body bytes around.
An imported function.
The storage for a WebAssembly global defined within the instance.
The fields compiled code needs to access to utilize a WebAssembly global variable imported from another instance.
Structure used to control interrupting wasm code.
The storage for a WebAssembly invocation argument
The fields compiled code needs to access to utilize a WebAssembly linear memory defined within the instance, namely the start address and the size in bytes.
The fields compiled code needs to access to utilize a WebAssembly linear memory imported from another instance.
An index into the shared signature registry, usable for checking signatures at indirect calls.
The fields compiled code needs to access to utilize a WebAssembly table defined within the instance.
The fields compiled code needs to access to utilize a WebAssembly table imported from another instance.
Enums
The value of an export passed from one instance to another.
An error while instantiating a module.
Representation of a runtime wasm linear memory.
The allocation strategy to use for the pooling instance allocator.
Represents an instance’s table.
An element going into or coming out of a table.
Stores trace message with backtrace.
Constants
Value returned by ResourceLimiter::instances
default method
Value returned by ResourceLimiter::memories
default method
Value returned by ResourceLimiter::tables
default method
Version number of this crate.
Traits
Represents a runtime instance allocator.
Used by the runtime to query module information.
Used by the runtime to lookup information about a module given a program counter value.
Used by hosts to limit resource consumption of instances.
A linear memory
A memory allocator
Dynamic runtime functionality needed by this crate throughout the execution of a wasm instance.
Functions
Catches any wasm traps that happen within the execution of closure
,
returning them as a Result
.
This function is required to be called before any WebAssembly is entered. This will configure global state such as signal handlers to prepare the process to receive wasm traps.
Raises a trap from inside library code immediately.
Raises a user-defined trap immediately.
Carries a Rust panic across wasm code and resumes the panic on the other side.
Eagerly initialize thread-local runtime functionality. This will be performed lazily by the runtime if users do not perform it eagerly.
Type Definitions
Function which may handle custom signals while processing traps.
Trampoline function pointer type.
