Struct InMemorySink 

pub struct InMemorySink { /* private fields */ }

In-memory sink that collects every recorded StepFact.

Useful for tests and for tooling that wants to inspect the fact stream without going through disk.

Implementations

impl InMemorySink

pub fn new() -> Self

Create an empty sink.

pub fn facts(&self) -> &[StepFact]

Recorded facts in the order they arrived.

pub fn len(&self) -> usize

Number of facts recorded so far.

pub fn is_empty(&self) -> bool

Whether any fact has been recorded.

Trait Implementations

impl Debug for InMemorySink

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

Formats the value using the given formatter.

impl Default for InMemorySink

fn default() -> InMemorySink

Returns the “default value” for a type.

impl TranscriptSink for InMemorySink

fn record(&mut self, at: DateTime<Utc>, fact: &StepFact) -> Result<()>

Record a single fact, stamped with the caller-supplied event time at. Must persist before returning, the file-backed implementation calls sync_data so a power loss after record returns cannot drop the fact.

fn finalize(&mut self) -> Result<TranscriptFingerprint>

Finalize the transcript and return its fingerprint.
