Union wasmer_vm::VMFunctionEnvironment

source · [−]

pub union VMFunctionEnvironment {
    pub vmctx: *mut VMContext,
    pub host_env: *mut c_void,
}

Expand description

Union representing the first parameter passed when calling a function.

It may either be a pointer to the VMContext if it’s a Wasm function or a pointer to arbitrary data controlled by the host if it’s a host function.

Fields

vmctx: *mut VMContext

Wasm functions take a pointer to VMContext.

host_env: *mut c_void

Host functions can have custom environments.
