Struct google_api_proto::google::cloud::datacatalog::v1beta1::ColumnSchema

pub struct ColumnSchema {
    pub column: String,
    pub type: String,
    pub description: String,
    pub mode: String,
    pub subcolumns: Vec<ColumnSchema>,
}

Representation of a column within a schema. Columns could be nested inside other columns.

Fields

column: String

Required. Name of the column.

type: String

Required. Type of the column.

description: String

Optional. Description of the column. Default value is an empty string.

mode: String

Optional. A column’s mode indicates whether the values in this column are required, nullable, etc. Only NULLABLE, REQUIRED and REPEATED are supported. Default mode is NULLABLE.

subcolumns: Vec<ColumnSchema>

Optional. Schema of sub-columns. A column can have zero or more sub-columns.

Trait Implementations

impl Clone for ColumnSchema

fn clone(&self) -> ColumnSchema

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnSchema

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

Formats the value using the given formatter.

impl Default for ColumnSchema

fn default() -> Self

Returns the “default value” for a type.

impl Message for ColumnSchema

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(&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,

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

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ColumnSchema

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