Union ValRaw

Source

pub union ValRaw {
    /* private fields */
}

Expand description

A “raw” and unsafe representation of a WebAssembly value.

This is provided for use with the Func::new_unchecked and Func::call_unchecked APIs. In general it’s unlikely you should be using this from Rust, rather using APIs like Func::wrap and TypedFunc::call.

This is notably an “unsafe” way to work with Val and it’s recommended to instead use Val where possible. An important note about this union is that fields are all stored in little-endian format, regardless of the endianness of the host system.
