Struct MapLn 

pub struct MapLn { /* private fields */ }

A MapLN maps a database ID to its configuration and state.

It lives in the database mapping tree (DbTree). Each MapLN holds:

• An underlying LN containing serialized database configuration
• A database ID
• Deleted flag (soft delete marker)
• Transient flag (for temporary databases)

Implementations

impl MapLn

pub fn new(db_id: u64, config_data: Vec<u8>) -> Self

Creates a new MapLN for the given database ID with configuration data.

Arguments

• db_id - The database ID
• config_data - Serialized database configuration

pub fn get_db_id(&self) -> u64

Returns the database ID.

pub fn is_deleted(&self) -> bool

Returns true if the database is marked as deleted.

pub fn set_deleted(&mut self, deleted: bool)

Sets the deleted flag.

pub fn is_transient(&self) -> bool

Returns true if the database is transient (temporary).

pub fn set_transient(&mut self, transient: bool)

Sets the transient flag.

pub fn get_ln(&self) -> &Ln

Returns a reference to the underlying LN.

pub fn get_ln_mut(&mut self) -> &mut Ln

Returns a mutable reference to the underlying LN.

pub fn log_size(&self) -> usize

Returns the serialized size of this MapLN.

pub fn write_to_log(&self, buf: &mut Vec<u8>)

Writes this MapLN to a byte buffer.

pub fn read_from_log(buf: &[u8]) -> Result<Self>

Reads a MapLN from a byte buffer.
