.coerce(target, value, state: XTwitterScraper::Internal::Type::Converter.new_coerce_state) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Based on target, transform value into target, to the extent possible:

  1. if the given value conforms to target already, return the given value
  2. if it's possible and safe to convert the given value to target, then the converted value
  3. otherwise, the given value unaltered

The coercion process is subject to improvement between minor release versions. See https://docs.pydantic.dev/latest/concepts/unions/#smart-mode

when we have to decide between multiple possible conversion targets:

  • true: the conversion must be exact, with minimum coercion.
  • false: the conversion can be approximate, with some coercion.

The exactness is Hash with keys being one of yes, no, or maybe. For any given conversion attempt, the exactness will be updated based on how closely the value recursively matches the target type:

  • yes: the value can be converted to the target type with minimum coercion.
  • maybe: the value can be converted to the target type with some reasonable coercion.
  • no: the value cannot be converted to the target type.

See implementation below for more details.

@option state [Boolean] :translate_names

@option state [Boolean] :strictness

@option state [Hash{Symbol=>Object}] :exactness

@option state [Class<StandardError>] :error

@option state [Integer] :branched

Parameters:

  • target (XTwitterScraper::Internal::Type::Converter, Class)
  • value (Object)
  • state (Hash{Symbol=>Object}) (defaults to: XTwitterScraper::Internal::Type::Converter.new_coerce_state) —

    The strictness is one of true, false. This informs the coercion strategy

Returns:

  • (Object)
