Struct tikv::storage::txn::commands::cleanup::Cleanup[−][src]

[+] Show declaration

pub struct Cleanup {
    pub ctx: Context,
    pub key: Key,
    pub start_ts: TimeStamp,
    pub current_ts: TimeStamp,
}

[−]

Rollback mutations on a single key.

This should be following a Prewrite on the given key.

Fields

ctx: Contextkey: Keystart_ts: TimeStamp

[−]

The transaction timestamp.

current_ts: TimeStamp

[−]

The approximate current ts when cleanup request is invoked, which is used to check the lock’s TTL. 0 means do not check TTL.

Implementations

`impl Cleanup`[src][−]

`pub fn new( key: Key, start_ts: TimeStamp, current_ts: TimeStamp, ctx: Context ) -> TypedCommand<()>`[src][−]

Return a TypedCommand that encapsulates the result of executing this command.
