Struct MemLogRegistry 

pub struct MemLogRegistry { /* private fields */ }

Process-shared registry of in-memory transaction logs, keyed by database name. It plays the role the log directory plays for VersionedLog: opening the same name (under any lease version) reaches the same records, so a mem-backed transactor recovers state across open/create calls within one process. Cloning a registry shares its storage.

Implementations

impl MemLogRegistry

pub fn new() -> Self

Creates an empty registry.

pub fn open(&self, name: &str, write_version: u64) -> MemVersionedLog

Opens the named log for writing under write_version, mirroring VersionedLog::open with in-memory storage.

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

Reports whether any records exist for the named log.

pub fn delete_all(&self, name: &str)

Discards every record for the named log.
