Struct ClientResponse 

pub struct ClientResponse {
    pub error: i32,
    pub metadata: Option<ErrorMetadata>,
    pub success_result: Option<SuccessResult>,
}

Fields

error: i32

metadata: Option<ErrorMetadata>

success_result: Option<SuccessResult>

Implementations

impl ClientResponse

pub fn error(&self) -> ErrorCode

Returns the enum value of error, or the default if the field is set to an invalid enum value.

pub fn set_error(&mut self, value: ErrorCode)

Sets error to the provided enum value.

impl ClientResponse

pub fn write_success() -> Self

Build success response for write operations

Returns

Response with Success code and result=true

pub fn cas_success() -> Self

Build CAS success response (comparison succeeded, value updated)

Returns

Response with Success code and result=true (CAS succeeded)

pub fn cas_failure() -> Self

Build CAS failure response (comparison failed, value NOT updated)

Returns

Response with Success code and result=false (CAS failed due to mismatch)

pub fn succeeded(&self) -> bool

Check if operation completed without error

Returns

• true if no error occurred (operation executed)
• false if error occurred or invalid response

pub fn is_write_success(&self) -> bool

Check if write operation succeeded with true result

Strict check for Put/Delete operations ensuring result is true. For CAS, use pattern matching to distinguish true/false results.

Returns

• true for successful Put/Delete (result must be true)
• false otherwise

pub fn read_results(results: Vec<ClientResult>) -> Self

Build success response for read operations

Parameters

• results: Vector of retrieved key-value pairs

pub fn client_error(error_code: ErrorCode) -> Self

Build generic error response for any operation type

Parameters

• error_code: Predefined client request error code

pub fn not_leader( leader_id: Option<String>, leader_address: Option<String>, ) -> Self

Build NOT_LEADER error response with leader metadata

Parameters

• leader_id: Optional leader node ID
• leader_address: Optional leader address

pub fn is_term_outdated(&self) -> bool

Check if this response indicates the leader’s term is outdated

pub fn is_quorum_timeout_or_failure(&self) -> bool

Check if this response indicates a quorum timeout or failure to receive majority responses

pub fn is_propose_failure(&self) -> bool

Check if this response indicates a failure to receive majority responses

pub fn is_retry_required(&self) -> bool

Check if this response indicates a a retry required

Trait Implementations

impl Clone for ClientResponse

fn clone(&self) -> ClientResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClientResponse

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

Formats the value using the given formatter.

impl Default for ClientResponse

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ClientResponse

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for ClientResponse

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where 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( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for ClientResponse

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

impl Serialize for ClientResponse

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
