Function namespaced 

pub fn namespaced(prefix: &str, key: &[u8]) -> Bytes

Creates a namespaced key by prefixing with the given prefix.

Uses a stack buffer for small keys (<=96 bytes) to avoid heap allocation during key construction. Returns Bytes which is cheap to clone into async blocks (just an atomic ref count increment after the initial copy).

Arguments

• prefix - The namespace prefix to prepend
• key - The key to namespace

Returns

A Bytes containing the prefixed key.
