Struct AppendAck 

#[non_exhaustive]
pub struct AppendAck {
    pub start: StreamPosition,
    pub end: StreamPosition,
    pub tail: StreamPosition,
}

Acknowledgement for an AppendInput.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

start: StreamPosition

Sequence number and timestamp of the first record that was appended.

end: StreamPosition

Sequence number of the last record that was appended + 1, and timestamp of the last record that was appended.

The difference between end.seq_num and start.seq_num will be the number of records appended.

tail: StreamPosition

Sequence number that will be assigned to the next record on the stream, and timestamp of the last record on the stream.

This can be greater than the end position in case of concurrent appends.

Trait Implementations

impl Clone for AppendAck

fn clone(&self) -> AppendAck

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppendAck

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

Formats the value using the given formatter.

impl From<AppendAck> for AppendAck

fn from(value: AppendAck) -> Self

Converts to this type from the input type.

impl PartialEq for AppendAck

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