Struct OutputSnapshot 

pub struct OutputSnapshot {
    pub scope: ScopeId,
    pub transaction_id: TransactionId,
    pub revision: Revision,
    pub state: Option<OutputPayload>,
    pub cleared: bool,
    pub frame: OutputFrameTrace,
}

Current ledger view for one materialized output.

Fields

scope: ScopeId

Scope that owns the output.

transaction_id: TransactionId

Last transaction that emitted a frame.

revision: Revision

Last revision observed for this output.

state: Option<OutputPayload>

Current consumer state after applying frames.

cleared: bool

Whether a clear frame has been observed.

frame: OutputFrameTrace

Last frame trace observed for this output.

Implementations

impl OutputSnapshot

pub fn state_as<T>(&self) -> Option<&T>

where T: Clone + PartialEq + Send + Sync + 'static,

Returns the current state downcast to the requested output payload type.

Trait Implementations

impl Clone for OutputSnapshot

fn clone(&self) -> OutputSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutputSnapshot

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

Formats the value using the given formatter.

impl PartialEq for OutputSnapshot

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