Struct spark_connect_rs::spark::expression::UnresolvedFunction

pub struct UnresolvedFunction {
    pub function_name: String,
    pub arguments: Vec<Expression>,
    pub is_distinct: bool,
    pub is_user_defined_function: bool,
}

An unresolved function is not explicitly bound to one explicit function, but the function is resolved during analysis following Sparks name resolution rules.

Fields

function_name: String

(Required) name (or unparsed name for user defined function) for the unresolved function.

arguments: Vec<Expression>

(Optional) Function arguments. Empty arguments are allowed.

is_distinct: bool

(Required) Indicate if this function should be applied on distinct values.

is_user_defined_function: bool

(Required) Indicate if this is a user defined function.

When it is not a user defined function, Connect will use the function name directly. When it is a user defined function, Connect will parse the function name first.

Trait Implementations

impl Clone for UnresolvedFunction

fn clone(&self) -> UnresolvedFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnresolvedFunction

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

Formats the value using the given formatter.

impl Default for UnresolvedFunction

fn default() -> Self

Returns the “default value” for a type.

impl Message for UnresolvedFunction

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 UnresolvedFunction

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