Struct ManifestRegistry 

pub struct ManifestRegistry<const N: usize> { /* private fields */ }

A static registry of all layout manifests for a program.

Pass this to identify_account or CLI tooling to decode arbitrary accounts from a program.

const MANIFESTS: ManifestRegistry<3> = ManifestRegistry::new(&[
    VAULT_MANIFEST,
    POOL_MANIFEST,
    POSITION_MANIFEST,
]);

if let Some((idx, manifest)) = MANIFESTS.identify(data) {
    // Found matching layout
}
