Implementations

impl Response

pub fn stored() -> Self

Create a STORED response.

pub fn not_stored() -> Self

pub fn deleted() -> Self

Create a DELETED response.

pub fn not_found() -> Self

Create a NOT_FOUND response.

pub fn ok() -> Self

Create an OK response.

pub fn numeric(value: u64) -> Self

Create a numeric response (from INCR/DECR).

pub fn miss() -> Self

Create an empty VALUES response (cache miss).

pub fn hit(key: &[u8], flags: u32, data: &[u8]) -> Self

Create a VALUES response with a single value (cache hit).

pub fn error() -> Self

Create an ERROR response.

pub fn client_error(msg: &[u8]) -> Self

Create a CLIENT_ERROR response.

pub fn server_error(msg: &[u8]) -> Self

Create a SERVER_ERROR response.

pub fn is_error(&self) -> bool

Returns true if this is an error response.

pub fn is_miss(&self) -> bool

Returns true if this represents a cache miss.

pub fn is_stored(&self) -> bool

Returns true if this is a successful storage response.

pub fn parse(data: &[u8]) -> Result<(Self, usize), ParseError>

Parse a response from a byte buffer.

Returns the parsed response and the number of bytes consumed.

pub fn encode(&self, buf: &mut [u8]) -> usize

Encode this response into a buffer.

Returns the number of bytes written.

pub fn encode_stored(buf: &mut [u8]) -> usize

Encode STORED directly to buffer.

pub fn encode_not_stored(buf: &mut [u8]) -> usize

Encode NOT_STORED directly to buffer.

pub fn encode_deleted(buf: &mut [u8]) -> usize

Encode DELETED directly to buffer.

pub fn encode_not_found(buf: &mut [u8]) -> usize

Encode NOT_FOUND directly to buffer.

pub fn encode_end(buf: &mut [u8]) -> usize

Encode END (empty get response) directly to buffer.

pub fn encode_value( buf: &mut [u8], key: &[u8], flags: u32, data: &[u8], ) -> usize

Encode a single VALUE response directly to buffer.

pub fn encode_value_with_cas( buf: &mut [u8], key: &[u8], flags: u32, data: &[u8], cas: u64, ) -> usize

Encode a single VALUE response with CAS token directly to buffer (GETS response).

Format: VALUE <key> <flags> <bytes> <cas>\r\n<data>\r\nEND\r\n

pub fn encode_exists(buf: &mut [u8]) -> usize

Encode EXISTS response directly to buffer.

pub fn encode_numeric(buf: &mut [u8], value: u64) -> usize

Encode a numeric response directly to buffer (INCR/DECR result).

pub fn encode_server_error(buf: &mut [u8], msg: &[u8]) -> usize

Encode a SERVER_ERROR response directly to buffer.

Trait Implementations

impl Clone for Response

fn clone(&self) -> Response

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Response

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

Formats the value using the given formatter.

impl PartialEq for Response

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