Trait WireSchema 

pub trait WireSchema {
    const FINGERPRINT: [u8; 32];
    const DESCRIPTOR: &'static str;
}

Layout fingerprint published by each wire struct via the #[derive(WireSchema)] proc-macro (defined in cc-lb-pdk-wasmtime-macros). The macro walks the struct AST, serialises fields to a canonical descriptor string, then embeds BLAKE3(descriptor) as a 32-byte const.

Required Associated Constants

const FINGERPRINT: [u8; 32]

const DESCRIPTOR: &'static str

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
