Struct OptionExposureSink

Source

pub struct OptionExposureSink(/* private fields */);

Expand description

A feed’s destination for complete exposure snapshots. Cheap to clone. Updates replace the latest snapshot without queuing or adding to computed gamma.

Implementations§

Source §

impl OptionExposureSink

Source

pub fn push(&self, value: OptionExposure) -> Result<(), FeedError>

Replace the held snapshot and wake the host. Refuse the whole snapshot for a nonfinite figure, invalid strike, expiry outside the query, different kind or over 100,000 rows. Report FeedError::InvalidData without changing the previous snapshot; an accepted push clears the error. Inactive sinks ignore pushes.

Source

pub fn report_error(&self, error: FeedError)

Report a failure, retaining the last accepted snapshot, and wake the host. Historical requests finish on this error; live requests can recover on a later push.

Source

pub fn is_active(&self) -> bool

Whether a consumer remains and, for a historical request, still awaits an answer.
