Struct UnresolvedAttribute

pub struct UnresolvedAttribute {
    pub unparsed_identifier: String,
    pub plan_id: Option<i64>,
}

An unresolved attribute that is not explicitly bound to a specific column, but the column is resolved during analysis by name.

Fields

unparsed_identifier: String

(Required) An identifier that will be parsed by Catalyst parser. This should follow the Spark SQL identifier syntax.

plan_id: Option<i64>

(Optional) The id of corresponding connect plan.

Implementations

impl UnresolvedAttribute

pub fn plan_id(&self) -> i64

Returns the value of plan_id, or the default value if plan_id is unset.

Trait Implementations

impl Clone for UnresolvedAttribute

fn clone(&self) -> UnresolvedAttribute

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnresolvedAttribute

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

Formats the value using the given formatter.

impl Default for UnresolvedAttribute

fn default() -> Self

Returns the “default value” for a type.

impl Message for UnresolvedAttribute

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 UnresolvedAttribute

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