PreparedWriteMetadata

Struct PreparedWriteMetadata 

Source 
pub struct PreparedWriteMetadata { /* private fields */ }
Expand description

What a write changes, without its value: its key, the revision it expects, its kind and the length of its value, if it has one.

Implementations§

Source§

impl PreparedWriteMetadata

Source

pub fn key(&self) -> &[u8] ⓘ

Source

pub fn expected(&self) -> Option<CommitSequence>

Source

pub fn live(&self) -> bool

Whether the write has a value; a write without one is a deletion.

Source

pub fn value_len(&self) -> Option<u64>

The length of the write’s value, if it has one.
