Struct Entry 

Source 
pub struct Entry<'a, M, C = Lexicographic> { /* private fields */ }
Expand description

One scanned key with an unread value descriptor.

Holding an entry borrows the tree, preventing mutation through that handle. Inspecting the key never reads the value payload.

Implementations§

Source§

impl<M: Memory, C: Comparator> Entry<'_, M, C>

Source

pub fn key(&self) -> &[u8] ⓘ

Borrow the encoded key.

Source

pub const fn value_len(&self) -> u64

Encoded value size, without loading its payload.

Source

pub fn value(&self) -> Result<Vec<u8>, Error>

Load and validate this entry’s value bytes.

§Errors

Returns an error on observed payload corruption.

Source

pub fn into_pair(self) -> Result<(Vec<u8>, Vec<u8>), Error>

Consume the entry and load its value.

§Errors

Returns an error on observed payload corruption.
