Implementations

impl Query

pub fn encode<B>(&self, buf: &mut B)where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<Query>, tag: u32, wire_type: WireType, buf: &mut B, ctx: DecodeContext ) -> Result<(), DecodeError>where B: Buf,

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

pub fn encoded_len(&self) -> usize

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

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl PartialEq<Query> for Query

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