Enum Boundary

pub enum Boundary {
    CurrentRow(bool),
    Unbounded(bool),
    Value(Box<Expression>),
}

Variants

CurrentRow(bool)

CURRENT ROW boundary

Unbounded(bool)

UNBOUNDED boundary. For lower bound, it will be converted to ‘UnboundedPreceding’. for upper bound, it will be converted to ‘UnboundedFollowing’.

Value(Box<Expression>)

This is an expression for future proofing. We are expecting literals on the server side.

Implementations

impl Boundary

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

where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<Boundary>, 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 Boundary

fn clone(&self) -> Boundary

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Boundary

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

Formats the value using the given formatter.

impl PartialEq for Boundary

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