Struct WindowRelFunction 

pub struct WindowRelFunction {
    pub function_reference: u32,
    pub arguments: Vec<FunctionArgument>,
    pub options: Vec<FunctionOption>,
    pub output_type: Option<Type>,
    pub phase: i32,
    pub invocation: i32,
    pub lower_bound: Option<Bound>,
    pub upper_bound: Option<Bound>,
    pub bounds_type: i32,
}

This message mirrors the WindowFunction message but removes the fields defining the partition, sorts, and bounds, since those must be consistent across the various functions in this rel. Refer to the WindowFunction message for a description of these fields.

Fields

function_reference: u32

References a function_anchor defined in this plan.

arguments: Vec<FunctionArgument>

options: Vec<FunctionOption>

output_type: Option<Type>

phase: i32

invocation: i32

lower_bound: Option<Bound>

Defines the lower bound of the window frame. Optional; defaults to the start of the partition. See Expression.WindowFunction.Bound.

upper_bound: Option<Bound>

Defines the upper bound of the window frame. Optional; defaults to the end of the partition. See Expression.WindowFunction.Bound.

bounds_type: i32

Defines how this function’s window bounds are interpreted. Must be ROWS or RANGE when either bound is CurrentRow, Preceding, or Following.

For RANGE with a Preceding or Following bound, sorts on the enclosing ConsistentPartitionWindowRel must contain exactly one ordering expression and must not use SORT_DIRECTION_CLUSTERED or a custom comparison function.

pub fn set_invocation(&mut self, value: AggregationInvocation)

Sets invocation to the provided enum value.

pub fn bounds_type(&self) -> BoundsType

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

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

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

impl Name for WindowRelFunction

const NAME: &'static str = "WindowRelFunction"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "substrait"

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.
