Struct LockedIndex 

pub struct LockedIndex {
    pub index: Index,
    /* private fields */
}

Exclusive handle to the index, backed by an advisory flock on .beans/index.lock.

Prevents concurrent read-modify-write races when multiple agents run in parallel. The lock is held from acquisition until save_and_release is called or the LockedIndex is dropped.

use bn::index::LockedIndex;
let mut locked = LockedIndex::acquire(beans_dir)?;
locked.index.beans[0].title = "Updated".to_string();
locked.save_and_release()?;

Fields

index: Index
