BijectionSchema

Finds the first field that matches the criteria used, and applies a bijection between the schema it holds and partial data, which ensures for the field's schema to be used as "top level" when decoding "payloads".

NB : a "payload" is typically a whole set of data, without a typical field-based splitting into subparts. This can be, for instance, an http body.

Finds whether a schema (or the underlying schema in the case of bijections/surjections, etc) is a primitive of a certain type.

Checks whether a schema is Unit or an empty structure

When applied on a structure schema, creates a schema that, when compiled into a codec, will only encode/decode a subset of the data, based on the hints of each field.

This can be used to only encode some fields of the data into the http body

Returns a SchemaPartition that indicates whether :

• no field match the condition
• some fields match the condition
• all fields match the condition
