Enum Payload 

pub enum Payload {
    Key(Frame),
    Patches(Vec<Patch>),
    Blob {
        hash: [u8; 32],
        bytes: Vec<u8>,
    },
}

One frame of a paint stream.

Variants

Key(Frame)

A whole frame: the start of a group a late member can begin from.

Patches(Vec<Patch>)

Changes to the frame the receiver holds, oldest first.

Blob

The encoded bytes an image item references by this blake3 hash.

Fields

hash: [u8; 32]

bytes: Vec<u8>

Implementations

impl Payload

pub fn encode(&self) -> Result<Vec<u8>, WireError>

Encode, refusing anything the relay would not forward.

Errors

WireError::TooLarge past MAX_PAYLOAD_BYTES; a codec error.

pub fn decode(bytes: &[u8]) -> Result<Payload, WireError>

Decode one frame’s bytes.

Errors

WireError for oversized or malformed bytes. A blob’s hash is the receiver’s to verify before it trusts the bytes.

pub fn is_key(bytes: &[u8]) -> bool

Whether bytes encode a Payload::Key, from the first byte alone.

Trait Implementations

impl Clone for Payload

fn clone(&self) -> Payload

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Payload

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Payload

fn deserialize<__D>( __deserializer: __D, ) -> Result<Payload, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Payload

fn eq(&self, other: &Payload) -> 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 Payload

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
