Module data_type

Data types that connect Parquet physical types with their Rust-specific representations.

Modules

• private 🔒

Macros

• ensure_phys_ty 🔒
  Macro to reduce repetition in making type assertions on the physical type against T
• gen_as_bytes 🔒
• make_type 🔒
• unimplemented_slice_as_bytes 🔒

Structs

• BoolType
  Parquet physical type: BoolType
• ByteArray
  Rust representation for BYTE_ARRAY and FIXED_LEN_BYTE_ARRAY Parquet physical types. Value is backed by a byte buffer.
• ByteArrayType
  Parquet physical type: ByteArrayType
• DoubleType
  Parquet physical type: DoubleType
• FixedLenByteArray
  Wrapper type for performance reasons, this represents FIXED_LEN_BYTE_ARRAY but in all other considerations behaves the same as ByteArray
• FixedLenByteArrayType
  Parquet physical type: FixedLenByteArrayType
• FloatType
  Parquet physical type: FloatType
• Int96
  Rust representation for logical type INT96, value is backed by an array of u32. The type only takes 12 bytes, without extra padding.
• Int32Type
  Parquet physical type: Int32Type
• Int64Type
  Parquet physical type: Int64Type
• Int96Type
  Parquet physical type: Int96Type

Enums

• Decimal
  Rust representation for Decimal values.

Traits

• AsBytes
  Converts an instance of data type to a slice of bytes as u8.
• DataType
  Contains the Parquet physical type information as well as the Rust primitive type presentation.
• SliceAsBytes
  Converts an slice of a data type to a slice of bytes.
• SliceAsBytesDataTypeDeprecated
