pub unsafe trait WasmPrimitive: Default { }Expand description
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.
§⚠️ Unstable
This is part of the internal convert module, no
stability guarantees are provided. Use at your own risk. See its
documentation for more details.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
