Struct RangeRequest

pub struct RangeRequest {
    pub header: Option<RequestHeader>,
    pub key: Vec<u8>,
    pub range_end: Vec<u8>,
    pub limit: i64,
    pub keys_only: bool,
}

Fields

header: Option<RequestHeader>

key: Vec<u8>

key is the first key for the range, If range_end is not given, the request only looks up key.

range_end: Vec<u8>

range_end is the upper bound on the requested range [key, range_end). If range_end is ‘\0’, the range is all keys >= key. If range_end is key plus one (e.g., “aa”+1 == “ab”, “a\xff”+1 == “b”), then the range request gets all keys prefixed with key. If both key and range_end are ‘\0’, then the range request returns all keys.

limit: i64

limit is a limit on the number of keys returned for the request. When limit is set to 0, it is treated as no limit.

keys_only: bool

keys_only when set returns only the keys and not the values.

Implementations

impl RangeRequest

pub fn set_header( &mut self, _: (u64, u64), role: Role, tracing_context: HashMap<String, String>, )

Trait Implementations

impl Clone for RangeRequest

fn clone(&self) -> RangeRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RangeRequest

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

Formats the value using the given formatter.

impl Default for RangeRequest

fn default() -> RangeRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RangeRequest

fn deserialize<__D>( __deserializer: __D, ) -> Result<RangeRequest, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for RangeRequest

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for RangeRequest

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

impl Serialize for RangeRequest

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
