[−][src]Struct rocks::merge_operator::MergeOperationInput
Fields
key: &'a &'a [u8]
The key associated with the merge operation.
existing_value: Option<&'a &'a [u8]>
The existing value of the current key, nullptr means that the value dont exist.
Implementations

[src]
pub fn key(&self) -> &[u8]ⓘ
[src]
The key associated with the merge operation.
pub fn existing_value(&self) -> Option<&[u8]>
[src]
The existing value of the current key, nullptr means that the value doesn't exist.
pub fn operands(&self) -> &[&[u8]]ⓘ
[src]
A list of operands to apply.
pub fn logger(&self) -> &Logger
[src]
Logger could be used by client to log any errors that happen during the merge operation.
