Enum FilePosition 

pub enum FilePosition {
    Beginning,
    End,
    Sequence(u64),
    Timestamp(u64),
}

A position in a stream file’s retained log, accepted by Seeker::seek.

Captured positions (Positioned::position) carry the pinned semantics the framework defines: seeking to one redelivers exactly that message (the transport’s sequence rewind is inclusive). The other forms keep the transport’s own semantics: Beginning replays everything retained, End skips to the tip, and Timestamp resumes at the earliest message strictly later than the instant (milliseconds since the Unix epoch).

Variants

Beginning

Everything retained.

End

The tip of the stream.

Sequence(u64)

A captured message sequence (inclusive).

Timestamp(u64)

Milliseconds since the Unix epoch (exclusive).

Implementations

impl FilePosition

pub const fn beginning() -> Self

Everything retained: FilePosition::Beginning.

pub const fn end() -> Self

The tip of the stream: FilePosition::End.

pub const fn sequence(sequence: u64) -> Self

A message sequence, redelivered inclusively: FilePosition::Sequence.

pub const fn timestamp(millis: u64) -> Self

Milliseconds since the Unix epoch, resuming strictly later: FilePosition::Timestamp.
