FakeJournalStore

Struct FakeJournalStore 

Source
pub struct FakeJournalStore { /* private fields */ }
Expand description

In-memory fake journal store fixture for SDK conformance tests. Use it to script deterministic behavior in memory; any transcript or endpoint mutation is documented on the method that performs it.

Implementations§

Source§

impl FakeJournalStore

Source

pub fn records(&self) -> Vec<JournalRecord>

Returns the records currently held by this value. This configures deterministic in-memory test state only.

Source

pub fn normalized_records(&self) -> Vec<Value>

Returns the normalized records currently held by this value. This reads deterministic in-memory test state and performs no external I/O.

Source

pub fn fail_next_append(&self, message: impl Into<String>)

Fail next append. This reads or mutates deterministic in-memory test state unless the method explicitly names a fixture file.

impl RunJournal for FakeJournalStore

Source§

fn append(&self, record: JournalRecord) -> Result<JournalCursor, AgentError>

Appends one durable journal record and returns its cursor. Implementations append one durable journal record and return its cursor; they must not execute the effect described by the record.
