Struct google_api_proto::google::spanner::executor::v1::KeyRange

pub struct KeyRange {
    pub start: Option<ValueList>,
    pub limit: Option<ValueList>,
    pub type: Option<i32>,
}

KeyRange represents a range of rows in a table or index.

A range has a start key and an end key. These keys can be open or closed, indicating if the range includes rows with that key.

Keys are represented by “ValueList”, where the ith value in the list corresponds to the ith component of the table or index primary key.

Fields

start: Option<ValueList>

“start” and “limit” must have the same number of key parts, though they may name only a prefix of the table or index key. The start key of this KeyRange.

limit: Option<ValueList>

The end key of this KeyRange.

type: Option<i32>

“start” and “limit” type for this KeyRange.

Implementations

impl KeyRange

pub fn type(&self) -> Type

Returns the enum value of type, or the default if the field is unset or set to an invalid enum value.

pub fn set_type(&mut self, value: Type)

Sets type to the provided enum value.

Trait Implementations

impl Clone for KeyRange

fn clone(&self) -> KeyRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyRange

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

Formats the value using the given formatter.

impl Default for KeyRange

fn default() -> Self

Returns the “default value” for a type.

impl Message for KeyRange

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 KeyRange

fn eq(&self, other: &KeyRange) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
