Struct googapis::google::cloud::bigquery::storage::v1beta1::TableReadOptions

pub struct TableReadOptions {
    pub selected_fields: Vec<String>,
    pub row_restriction: String,
}

Options dictating how we read a table.

Fields

selected_fields: Vec<String>

Optional. Names of the fields in the table that should be read. If empty, all fields will be read. If the specified field is a nested field, all the sub-fields in the field will be selected. The output field order is unrelated to the order of fields in selected_fields.

row_restriction: String

Optional. SQL text filtering statement, similar to a WHERE clause in a query. Aggregates are not supported.

Examples: “int_field > 5” “date_field = CAST(‘2014-9-27’ as DATE)” “nullable_field is not NULL” “st_equals(geo_field, st_geofromtext(“POINT(2, 2)”))“ “numeric_field BETWEEN 1.0 AND 5.0”

Trait Implementations

impl Clone for TableReadOptions

fn clone(&self) -> TableReadOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableReadOptions

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

Formats the value using the given formatter.

impl Default for TableReadOptions

fn default() -> Self

Returns the “default value” for a type.

impl Message for TableReadOptions

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

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, 

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

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

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

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

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

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

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

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, 

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

impl PartialEq<TableReadOptions> for TableReadOptions

fn eq(&self, other: &TableReadOptions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &TableReadOptions) -> bool

This method tests for !=.
