Module parquet::schema::types

Expand description

Contains structs and methods to build Parquet schema and schema descriptors.

Structs§

  • Basic type info. This contains information such as the name of the type, the repetition level, the logical type and the kind of the type (group, primitive).
  • A descriptor for leaf-level primitive columns. This encapsulates information such as definition and repetition levels and is used to re-assemble nested data.
  • Represents a path in a nested schema
  • A builder for group types. All attributes are optional except the name. Note that if not specified explicitly, None is used as the repetition of the group, which means it is a root (message) type.
  • A builder for primitive types. All attributes are optional except the name and physical type. Note that if not specified explicitly, Repetition::OPTIONAL is used.
  • A schema descriptor. This encapsulates the top-level schemas for all the columns, as well as all descriptors for all the primitive columns.

Enums§

  • Representation of a Parquet type. Used to describe primitive leaf fields and structs, including top-level schema. Note that the top-level schema type is represented using GroupType whose repetition is None.
