Struct ProtoKeyError 

pub struct ProtoKeyError {
    pub locked: Option<LockInfo>,
    pub retryable: String,
    pub abort: String,
    pub conflict: Option<WriteConflict>,
    pub already_exist: Option<AlreadyExist>,
    pub deadlock: Option<Deadlock>,
    pub commit_ts_expired: Option<CommitTsExpired>,
    pub txn_not_found: Option<TxnNotFound>,
    pub commit_ts_too_large: Option<CommitTsTooLarge>,
    pub assertion_failed: Option<AssertionFailed>,
    pub primary_mismatch: Option<PrimaryMismatch>,
}

Protobuf-generated per-key error returned by TiKV.

This type is generated from TiKV’s protobuf definitions and may change in a future release even if the wire format is compatible.

Fields

locked: Option<LockInfo>

Client should backoff or cleanup the lock then retry.

retryable: String

Client may restart the txn. e.g write conflict.

abort: String

Client should abort the txn.

conflict: Option<WriteConflict>

Write conflict is moved from retryable to here.

already_exist: Option<AlreadyExist>

Key already exists

deadlock: Option<Deadlock>

Deadlock is used in pessimistic transaction for single statement rollback.

commit_ts_expired: Option<CommitTsExpired>

Commit ts is earlier than min commit ts of a transaction.

txn_not_found: Option<TxnNotFound>

Txn not found when checking txn status.

commit_ts_too_large: Option<CommitTsTooLarge>

Calculated commit TS exceeds the limit given by the user.

assertion_failed: Option<AssertionFailed>

Assertion of a Mutation is evaluated as a failure.

primary_mismatch: Option<PrimaryMismatch>

CheckTxnStatus is sent to a lock that’s not the primary.

Trait Implementations

impl Clone for KeyError

fn clone(&self) -> KeyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyError

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

Formats the value using the given formatter.

impl Default for KeyError

fn default() -> Self

Returns the “default value” for a type.

impl From<KeyError> for Error

fn from(e: ProtoKeyError) -> Error

Converts to this type from the input type.

impl Message for KeyError

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for KeyError

fn eq(&self, other: &KeyError) -> 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.
