end

#encryption_personalization(val = nil) ⇒ String

Personalization string for BLAKE2b key derivation in XChaCha20Poly1305. This provides cryptographic domain separation, ensuring derived keys are unique per application even with identical master keys and contexts. Must be 16 bytes or less (automatically padded with null bytes).

end

Examples:

Familia.configure do |config|

config.encryption_personalization = 'MyApp1.0'

Parameters:

  • val (String, nil) (defaults to: nil) —

    The personalization string, or nil to get current value

Returns:

  • (String) —

    Current personalization string

#transaction_mode(val = nil) ⇒ Symbol

Controls transaction behavior when connection handlers don't support transactions

Available modes:

  • :warn (default): Log warning and execute commands individually
  • :strict: Raise OperationModeError when transaction unavailable
  • :permissive: Silently execute commands individually

Examples:

Setting transaction mode

Familia.configure do |config|
  config.transaction_mode = :warn
end

Parameters:

  • val (Symbol, nil) (defaults to: nil) —

    The transaction mode or nil to get current value

Returns:

  • (Symbol) —

    Current transaction mode (:strict, :warn, :permissive)

Instance Method Details

#configure {|Settings| ... } ⇒ Settings Also known as: config

Configure Familia settings

Examples:

Block-based configuration

Familia.configure do |config|
  config.redis_uri = "redis://localhost:6379/1"
  config.ttl = 3600
end

Method chaining

Familia.configure.redis_uri = "redis://localhost:6379/1"

Yields:

  • (Settings) —

    self for block-based configuration

Returns:

  • (Settings) —

    self for method chaining

def configure
  yield self if block_given?
  self
end

#default_suffix ⇒ Object

We define this do-nothing method because it reads better than simply Familia.suffix in some contexts.

end

#pipeline_mode(val = nil) ⇒ Symbol

Controls pipeline behavior when connection handlers don't support pipelines

Available modes:

  • :warn (default): Log warning and execute commands individually
  • :strict: Raise OperationModeError when pipeline unavailable
  • :permissive: Silently execute commands individually

Examples:

Setting pipeline mode

Familia.configure do |config|
  config.pipeline_mode = :permissive
end

Parameters:

  • val (Symbol, nil) (defaults to: nil) —

    The pipeline mode or nil to get current value

Returns:

  • (Symbol) —

    Current pipeline mode (:strict, :warn, :permissive)
