Struct AppendAck 

pub struct AppendAck {
    pub start: Option<StreamPosition>,
    pub end: Option<StreamPosition>,
    pub tail: Option<StreamPosition>,
}

Success response message to an Append request.

Fields

start: Option<StreamPosition>

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

end: Option<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: Option<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 Default for AppendAck

fn default() -> Self

Returns the “default value” for a type.

impl From<AppendAck> for AppendAck

fn from(_: AppendAck) -> Self

Converts to this type from the input type.

impl Hash for AppendAck

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for AppendAck

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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.
