pub struct CloudSpannerProperties {
    pub database: String,

}

Connection properties specific to Cloud Spanner.

Fields

database: String

Cloud Spanner database in the form `project/instance/database’

use_parallelism: bool

If parallelism should be used when reading from Cloud Spanner

max_parallelism: i32

Allows setting max parallelism per query when executing on Spanner independent compute resources. If unspecified, default values of parallelism are chosen that are dependent on the Cloud Spanner instance configuration.

REQUIRES: use_parallelism must be set. REQUIRES: Either use_data_boost or use_serverless_analytics must be set.

use_serverless_analytics: bool

If the serverless analytics service should be used to read data from Cloud Spanner. Note: use_parallelism must be set when using serverless analytics.

use_data_boost: bool

If set, the request will be executed via Spanner independent compute resources. REQUIRES: use_parallelism must be set.

NOTE: use_serverless_analytics will be deprecated. Prefer use_data_boost over use_serverless_analytics.

database_role: String

Optional. Cloud Spanner database role for fine-grained access control. The Cloud Spanner admin should have provisioned the database role with appropriate permissions, such as SELECT and INSERT. Other users should only use roles provided by their Cloud Spanner admins.

For more details, see [About fine-grained access control] (https://cloud.google.com/spanner/docs/fgac-about).

REQUIRES: The database role name must start with a letter, and can only contain letters, numbers, and underscores.

Trait Implementations

impl Clone for CloudSpannerProperties

fn clone(&self) -> CloudSpannerProperties

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CloudSpannerProperties

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

Formats the value using the given formatter.

impl Default for CloudSpannerProperties

fn default() -> Self

Returns the “default value” for a type.

impl Message for CloudSpannerProperties

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 CloudSpannerProperties

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