Struct cassandra_protocol::frame::frame_encoder::LegacyFrameEncoder

pub struct LegacyFrameEncoder { /* private fields */ }

Pre-V5 frame encoder which simply encodes one envelope directly in the buffer.

Trait Implementations

impl Clone for LegacyFrameEncoder

fn clone(&self) -> LegacyFrameEncoder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LegacyFrameEncoder

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

Formats the value using the given formatter.

impl Default for LegacyFrameEncoder

fn default() -> LegacyFrameEncoder

Returns the “default value” for a type.

impl FrameEncoder for LegacyFrameEncoder

fn can_fit(&self, _len: usize) -> bool

Determines if payload of given size can fit in current frame buffer.

fn reset(&mut self)

Resets the internal state and prepares it for encoding envelopes.

fn add_envelope(&mut self, envelope: Vec<u8>)

Adds a self-contained envelope to current frame.

fn finalize_self_contained(&mut self) -> &[u8]

Finalizes a self-contained encoded frame in the buffer.

fn finalize_non_self_contained(&mut self, envelope: &[u8]) -> (usize, &[u8])

Appends a large envelope and finalizes non self-contained encoded frame in the buffer. Copies as much envelope data as possible and returns new envelope buffer start.

fn has_envelopes(&self) -> bool

Checks if current frame contains any envelopes.
