Struct NamespaceManager 

pub struct NamespaceManager { /* private fields */ }

Namespace-aware key manager

This provides utilities for working with multiple namespaces and extracting namespace information from keys.

Implementations

impl NamespaceManager

pub fn new() -> Self

Create a new namespace manager with the default separator

pub fn with_separator<S: Into<String>>(separator: S) -> Result<Self>

Create a new namespace manager with a custom separator

pub fn separator(&self) -> &str

Get the separator used by this manager

pub fn namespace<S: Into<String>>(&self, name: S) -> Result<Namespace>

Create a namespace

pub fn parse_key<K: AsRef<[u8]>>( &self, namespaced_key: K, ) -> Option<(String, Bytes)>

Extract namespace and key from a namespaced key

Arguments

• namespaced_key - The full namespaced key

Returns

A tuple of (namespace_name, original_key) if the key is namespaced, or None if it’s not in namespace format

pub fn extract_namespaces<'a, I, K>(&self, keys: I) -> Vec<String>

where I: Iterator<Item = &'a K>, K: AsRef<[u8]> + 'a,

Get all unique namespace names from a collection of keys

Arguments

• keys - Iterator over keys to analyze

Returns

A vector of unique namespace names found in the keys

pub fn key_belongs_to_namespace<K: AsRef<[u8]>>( &self, key: K, namespace_name: &str, ) -> bool

Check if a key belongs to a specific namespace
