Struct Mutation 

pub struct Mutation {
    pub handle: MessageHandle,
    pub revision: u32,
    pub change: Change,
}

An owned transcript mutation (see MessageMutation).

Fields

handle: MessageHandle

revision: u32

Apply only if newer than the last revision applied for handle.

change: Change

Implementations

impl Mutation

pub fn from_engine<'e>( mutation: MessageMutation, body: impl Fn(&BodyRef) -> &'e str, sender_key: impl FnOnce(ConversationKey, SenderScope) -> Option<PublicKey>, ) -> Self

The owned form of one of the engine’s mutations, read while it is fresh: body is Engine::body until the engine’s queue empties. sender_key gives the full key behind a sender scope, where one is known.

pub fn describes_receipt(&self) -> bool

Whether this record describes content that arrived in the frame that produced it, as opposed to an outbound echo, a gap placeholder, or a change to an earlier message. Radio metadata belongs only on these.

Trait Implementations

impl Clone for Mutation

fn clone(&self) -> Mutation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mutation

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

Formats the value using the given formatter.

impl PartialEq for Mutation

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