Struct MacroManager 

pub struct MacroManager { /* private fields */ }

Macro catalog manager.

Owns the in-memory macro map with optional persistence and WAL backing, mirroring super::sequence_manager::SequenceManager. Thread-safe via parking_lot::RwLock.

Implementations

impl MacroManager

pub fn new() -> Self

Create a new MacroManager without persistence.

pub fn with_storage(storage: Arc<dyn MacroStorage>) -> Self

Create a new MacroManager with a persistence backend.

pub fn with_wal( storage: Arc<dyn MacroStorage>, wal_writer: Arc<Mutex<dyn WalWriter>>, ) -> Self

Create a new MacroManager with persistence and WAL support.

pub fn initialize(&self) -> Result<(), StorageError>

Initialize by loading all macros from storage.

pub fn validate_definition(def: &MacroDef) -> Result<(), StorageError>

Validate a macro definition structurally (no catalog access).

Checks: non-empty name, no duplicate parameter names, and that the body only references declared parameters or globals. Unknown Expression::Variable leaves that are not parameters are treated as query variables (allowed); direct self-reference by macro name in a nested call is rejected at expansion time.

pub fn create_macro(&self, def: MacroDef) -> Result<(), StorageError>

Create a new macro definition.

pub fn drop_macro(&self, name: &str) -> Result<(), StorageError>

Drop (delete) a macro definition.

pub fn get_macro(&self, name: &str) -> Option<Arc<MacroDef>>

Look up a macro definition by name (case-insensitive).

pub fn exists(&self, name: &str) -> bool

Check if a macro exists (case-insensitive).

pub fn list_macros(&self) -> Vec<Arc<MacroDef>>

List all macro definitions, ordered by name for stable output.

pub fn replay_create(&self, redo: &CreateMacroRedo) -> Result<(), StorageError>

Replay a WAL CreateMacro record during recovery.

pub fn replay_drop(&self, redo: &DropMacroRedo) -> Result<(), StorageError>

Replay a WAL DropMacro record during recovery.

Trait Implementations

impl Debug for MacroManager

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

Formats the value using the given formatter.

impl Default for MacroManager

fn default() -> Self

Returns the “default value” for a type.
