Enum DataFrame 

pub enum DataFrame {
    Whole {
        seq: Seq,
        state: Repr,
    },
    Ops {
        seq: Seq,
        ops: Vec<Op>,
    },
}

A data patch frame: what a Mode B subscription carries instead of DOM ops (§5.1).

Two shapes rather than one, and the difference is the same one Resumption draws for Mode A: a client with nothing gets the accumulator, and a client with a position gets the difference from it. beck_core::delta is the vocabulary; this is the envelope it travels in.

Variants

Whole

{"t":"s","q":<seq>,"v":<state>} — the whole accumulator, for a client with no position.

Fields

seq: Seq

state: Repr

Ops

{"t":"d","q":<seq>,"o":[<op>...]} — the difference, for a client that has one.

Fields

seq: Seq

ops: Vec<Op>

Implementations

impl DataFrame

pub fn whole(seq: Seq, state: &Value) -> Option<DataFrame>

The whole accumulator, or nothing if it holds something unstorable — which the checker makes unreachable (B0411), and which is a refusal rather than a fabrication here.

pub fn seq(&self) -> Seq

pub fn is_empty(&self) -> bool

pub fn to_json(&self) -> Value

Trait Implementations

impl Clone for DataFrame

fn clone(&self) -> DataFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataFrame

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

Formats the value using the given formatter.

impl PartialEq for DataFrame

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