[−][src]Crate substrate_wasmtime_runtime
Runtime library support for Wasmtime.
Modules
| libcalls | Runtime library calls. |
Structs
| ExportFunction | A function export value. |
| ExportGlobal | A global export value. |
| ExportMemory | A memory export value. |
| ExportTable | A table export value. |
| 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. |
| Table | A table instance. |
| 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. |
| VMInterrupts | Structure used to control interrupting wasm code, currently with only one atomic flag internally used. |
| 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. |
Traits
| RuntimeLinearMemory | A linear memory |
| RuntimeMemoryCreator | A memory allocator |
Functions
| catch_traps⚠ | Catches any wasm traps that happen within the execution of |
| init_traps | This function performs the low-overhead signal handler initialization that we want to do eagerly to ensure a more-deterministic global process state. |
| raise_lib_trap⚠ | Raises a trap from inside library code immediately. |
| 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. |
Type Definitions
| SignalHandler | Function which may handle custom signals while processing traps. |
| VMTrampoline |
