Struct datafusion_proto::generated::datafusion::WindowFrame

pub struct WindowFrame {
    pub window_frame_units: i32,
    pub start_bound: Option<WindowFrameBound>,
    pub end_bound: Option<EndBound>,
}

Fields

window_frame_units: i32

start_bound: Option<WindowFrameBound>

end_bound: Option<EndBound>

“optional” keyword is stable in protoc 3.15 but prost is still on 3.14 (see https://github.com/tokio-rs/prost/issues/430 and https://github.com/tokio-rs/prost/pull/455) this syntax is ugly but is binary compatible with the “optional” keyword (see https://stackoverflow.com/questions/42622015/how-to-define-an-optional-field-in-protobuf-3)

Implementations

impl WindowFrame

pub fn window_frame_units(&self) -> WindowFrameUnits

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

pub fn set_window_frame_units(&mut self, value: WindowFrameUnits)

Sets window_frame_units to the provided enum value.

Trait Implementations

impl Clone for WindowFrame

fn clone(&self) -> WindowFrame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowFrame

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

Formats the value using the given formatter.

impl Default for WindowFrame

fn default() -> Self

Returns the “default value” for a type.

impl Message for WindowFrame

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, Global> 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, Global> 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<WindowFrame> for WindowFrame

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

impl TryFrom<&WindowFrame> for WindowFrame

type Error = Error

The type returned in the event of a conversion error.

fn try_from(window: &WindowFrame) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<WindowFrame> for WindowFrame

type Error = Error

The type returned in the event of a conversion error.

fn try_from(window: WindowFrame) -> Result<Self, Self::Error>

Performs the conversion.
