Enum Frame 

pub enum Frame {
    Simple(String),
    Error(String),
    Integer(i64),
    Bulk(Bytes),
    Array(Vec<Frame>),
    Null,
    Map(Vec<(Frame, Frame)>),
}

A single RESP3 protocol frame.

Covers the core types needed for basic Redis-compatible commands: strings, errors, integers, bulk data, arrays, null, and maps.

Variants

Simple(String)

Simple string response, e.g. +OK\r\n. Used for short, non-binary status replies.

Error(String)

Error response, e.g. -ERR unknown command\r\n.

Integer(i64)

64-bit signed integer, e.g. :42\r\n.

Bulk(Bytes)

Bulk (binary-safe) string, e.g. $5\r\nhello\r\n. Uses Bytes for zero-copy-friendly handling.

Array(Vec<Frame>)

Ordered array of frames, e.g. *2\r\n+hello\r\n+world\r\n.

Null

Null value, e.g. _\r\n.

Map(Vec<(Frame, Frame)>)

Ordered map of key-value frame pairs, e.g. %1\r\n+key\r\n+val\r\n.

Implementations

impl Frame

pub fn serialize(&self, dst: &mut BytesMut)

Serializes this frame into the provided buffer.

Writes the full RESP3 wire representation, including type prefix and trailing \r\n delimiters.

impl Frame

pub fn is_null(&self) -> bool

Returns true if this frame is a null value.

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Frame

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

Formats the value using the given formatter.

impl PartialEq for Frame

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