utils/format

A function that converts data from one format to another.

This is commonly used for transforming message content blocks between different provider-specific formats and standardized internal representations.

A pair of bidirectional conversion functions for transforming data between two formats.

This type is used throughout the message system to enable conversion between provider-specific message formats (like OpenAI, Anthropic, Google, etc.) and standardized internal content block representations. The encode function typically converts from a standard format to a provider-specific format, while decode converts from a provider-specific format back to the standard format.
