[−][src]Crate wasmtime_runtime
Runtime library support for Wasmtime.
Modules
libcalls | Runtime library calls. Note that wasm compilers may sometimes perform these inline rather than calling them, particularly when CPUs have special instructions which compute them directly. |
Structs
GdbJitImageRegistration | Registeration for JIT image |
Imports | Resolved import pointers. |
InstanceHandle | A handle holding an |
LinkError | An link error while instantiating a module. |
Mmap | A simple struct consisting of a page-aligned pointer to page-aligned and initially-zeroed memory and a length. |
SignatureRegistry | WebAssembly requires that the caller and callee signatures in an indirect call must match. To implement this efficiently, keep a registry of all signatures, shared by all instances, so that call sites can just do an index comparison. |
TrapDescription | Description of a trap. |
TrapRegistration | RAII structure returned from |
TrapRegistry | The registry maintains descriptions of traps in currently allocated functions. |
VMCallerCheckedAnyfunc | 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. |
VMContext | The VM "context", which is pointed to by the |
VMFunctionBody | 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. |
VMFunctionImport | An imported function. |
VMGlobalDefinition | The storage for a WebAssembly global defined within the instance. |
VMGlobalImport | The fields compiled code needs to access to utilize a WebAssembly global variable imported from another instance. |
VMInvokeArgument | The storage for a WebAssembly invocation argument |
VMMemoryDefinition | 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. |
VMMemoryImport | The fields compiled code needs to access to utilize a WebAssembly linear memory imported from another instance. |
VMSharedSignatureIndex | An index into the shared signature registry, usable for checking signatures at indirect calls. |
VMTableDefinition | The fields compiled code needs to access to utilize a WebAssembly table defined within the instance. |
VMTableImport | The fields compiled code needs to access to utilize a WebAssembly table imported from another instance. |
Enums
Export | The value of an export passed from one instance to another. |
InstantiationError | An error while instantiating a module. |
Trap | Stores trace message with backtrace. |
Constants
VERSION | Version number of this crate. |
Functions
catch_traps⚠ | Catches any wasm traps that happen within the execution of |
raise_user_trap⚠ | Raises a user-defined trap immediately. |
resume_panic⚠ | Carries a Rust panic across wasm code and resumes the panic on the other side. |
wasmtime_call_trampoline⚠ | Call the wasm function pointed to by |
