Trait wasm_bindgen::convert::WasmPrimitive

pub unsafe trait WasmPrimitive: Default { }

A trait for any type which maps to a Wasm primitive type when used in FFI (i32, i64, f32, or f64).

This is with the exception of () (and other zero-sized types), which are also allowed because they’re ignored: no arguments actually get added.

Safety

This is an unsafe trait to implement as there’s no guarantee the type actually maps to a primitive type.
