Struct RowidAllocator 

pub struct RowidAllocator { /* private fields */ }

Implementations

impl RowidAllocator

pub fn get_next_rowid(&self) -> Option<(i64, Option<i64>)>

Lock-free rowid allocation via atomic CAS. Returns None only when at i64::MAX (triggers random fallback). Returns Some((new_rowid, prev_rowid)) where prev_rowid is None if table was empty.

pub fn insert_row_id_maybe_update(&self, rowid: i64)

Bump the counter to at least rowid. Used for user-specified rowids (e.g. INSERT INTO t(rowid,…) VALUES(1000,…)).

pub fn is_uninitialized(&self) -> bool

pub fn initialize(&self, rowid: Option<i64>)

Initialize from btree max. Called once per table, under lock.

pub fn lock(&self) -> bool

pub fn unlock(&self)

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