Struct WatchCreateRequest 

pub struct WatchCreateRequest {
    pub key: Vec<u8>,
    pub range_end: Vec<u8>,
    pub start_revision: i64,
    pub progress_notify: bool,
    pub filters: Vec<i32>,
    pub prev_kv: bool,
}

Fields

key: Vec<u8>

key is the key to register for watching.

range_end: Vec<u8>

range_end is the end of the range [key, range_end) to watch. If range_end is not given, only the key argument is watched. If range_end is equal to ‘\0’, all keys greater than or equal to the key argument are watched. If the range_end is one bit larger than the given key, then all keys with the prefix (the given key) will be watched.

start_revision: i64

start_revision is an optional revision to watch from (inclusive). No start_revision is “now”.

progress_notify: bool

progress_notify is set so that the etcd server will periodically send a WatchResponse with no events to the new watcher if there are no recent events. It is useful when clients wish to recover a disconnected watcher starting from a recent known revision. The etcd server may decide how often it will send notifications based on current load.

filters: Vec<i32>

filters filter the events at server side before it sends back to the watcher.

prev_kv: bool

If prev_kv is set, created watcher gets the previous KV before the event happens. If the previous KV is already compacted, nothing will be returned.

Implementations

impl WatchCreateRequest

pub fn filters( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(i32) -> Option<FilterType>>

Returns an iterator which yields the valid enum values contained in filters.

pub fn push_filters(&mut self, value: FilterType)

Appends the provided enum value to filters.

Trait Implementations

impl Clone for WatchCreateRequest

fn clone(&self) -> WatchCreateRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WatchCreateRequest

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

Formats the value using the given formatter.

impl Default for WatchCreateRequest

fn default() -> Self

Returns the “default value” for a type.

impl Hash for WatchCreateRequest

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 WatchCreateRequest

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 WatchCreateRequest

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