Struct wasmer_vm::SignatureRegistry [−][src]
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.
Implementations
impl SignatureRegistry[src]
pub fn new() -> Self[src]
Create a new SignatureRegistry.
pub fn register(&self, sig: &FunctionType) -> VMSharedSignatureIndex[src]
Register a signature and return its unique index.
pub fn lookup(&self, idx: VMSharedSignatureIndex) -> Option<FunctionType>[src]
Looks up a shared signature index within this registry.
Note that for this operation to be semantically correct the idx must
have previously come from a call to register of this same object.
