Struct SchemaRegistry 

pub struct SchemaRegistry { /* private fields */ }

Registry mapping key prefixes to table names.

Thread-safe for concurrent reads with occasional writes. Prefixes are matched using longest-prefix-first semantics.

Implementations

impl SchemaRegistry

pub fn new() -> Self

Create a new empty registry.

pub fn bypass() -> Self

Create a registry that bypasses all routing (returns default table).

Use this for SQLite where table partitioning has no benefit.

pub fn register(&self, prefix: &str, table_name: &str)

Register a prefix to route to a specific table.

Multiple prefixes can map to the same table. Longer prefixes take precedence over shorter ones.

Arguments

• prefix - Key prefix to match (e.g., “view:users:”)
• table_name - Target table name (e.g., “users_items”)

pub fn unregister(&self, prefix: &str) -> bool

Unregister a prefix.

Returns true if the prefix was found and removed.

pub fn table_for_key(&self, key: &str) -> &'static str

Get the table name for a given key.

Uses longest-prefix-first matching. Returns DEFAULT_TABLE if no prefix matches or if bypass mode is enabled.

pub fn prefixes_for_table(&self, table_name: &str) -> Vec<String>

Get all registered prefixes for a table.

pub fn tables(&self) -> Vec<String>

Get all registered tables (excluding default).

pub fn len(&self) -> usize

Get the number of registered prefixes.

pub fn is_empty(&self) -> bool

Check if the registry is empty.

pub fn is_bypass(&self) -> bool

Check if bypass mode is enabled.

pub fn clear(&self)

Clear all registered prefixes.

Trait Implementations

impl Debug for SchemaRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SchemaRegistry

fn default() -> Self

Returns the “default value” for a type.
