Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the Tpu Client class.

See Configuration for a description of the configuration fields.

Yields

(config) — Configure the Client client.

Yield Parameter

config (Client::Configuration)

Returns

(Client::Configuration)

Example

# Modify the configuration for all Tpu clients
::Google::Cloud::Tpu::V1::Tpu::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the Tpu Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

See Configuration for a description of the configuration fields.

Yields

(config) — Configure the Client client.

Yield Parameter

config (Client::Configuration)

Returns

(Client::Configuration)
