Trait Implementations

impl<'tx, 'p> BucketApi<'tx> for BucketImpl<'tx, 'p>

fn root(&self) -> PgId

Returns the bucket’s root page id.

fn writable(&self) -> bool

Returns whether the bucket is writable.

fn cursor<'a>(&'a self) -> CursorImpl<'tx, 'a>

Creates a cursor associated with the bucket.

fn bucket<'a, T: AsRef<[u8]>>(&'a self, name: T) -> Option<BucketImpl<'tx, 'a>>

Retrieves a nested bucket by name.

fn get<T: AsRef<[u8]>>(&self, key: T) -> Option<&[u8]>

Retrieves the value for a key in the bucket.

fn sequence(&self) -> u64

Returns the current integer for the bucket without incrementing it.

fn for_each<F: FnMut(&'tx [u8], Option<&'tx [u8]>) -> Result<()>>( &self, f: F, ) -> Result<()>

👎Deprecated since 1.3.9: please use iter_* methods instead

Executes a function for each key/value pair in a bucket. Because this uses a crate::CursorApi, the iteration over keys is in lexicographical order.

fn for_each_bucket<F: FnMut(&'tx [u8]) -> Result<()>>(&self, f: F) -> Result<()>

👎Deprecated since 1.3.9: please use iter_* methods instead

Executes a function for each bucket in a bucket. Because this function uses a crate::CursorApi, the iteration over keys is in lexicographical order.

fn stats(&self) -> BucketStats

Returns stats on a bucket.

fn iter_entries<'a>(&'a self) -> EntryIter<'tx, 'a>

fn iter_buckets<'a>(&'a self) -> BucketIter<'tx, 'a>
