Enum TxOperation 

pub enum TxOperation {
    Put {
        key: String,
        value: Vec<u8>,
        prev_value: Option<Vec<u8>>,
    },
    Delete {
        key: String,
        prev_value: Vec<u8>,
    },
    BatchPut {
        entries: Vec<(String, Vec<u8>)>,
    },
}

A single operation recorded inside a transaction.

Variants

Put

Insert or overwrite a key. prev_value holds the prior content for rollback.

Fields

key: String

value: Vec<u8>

prev_value: Option<Vec<u8>>

Delete

Remove a key. prev_value holds the prior content for rollback.

Fields

key: String

prev_value: Vec<u8>

BatchPut

Insert or overwrite multiple keys atomically.

Fields

entries: Vec<(String, Vec<u8>)>

Implementations

impl TxOperation

pub fn key_count(&self) -> usize

Returns the number of logical key-value pairs affected by this operation.

Trait Implementations

impl Clone for TxOperation

fn clone(&self) -> TxOperation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TxOperation

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

Formats the value using the given formatter.

impl Eq for TxOperation

impl PartialEq for TxOperation

fn eq(&self, other: &TxOperation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
