[]

Rust representation for Decimal values.

This is not a representation of Parquet physical type, but rather a wrapper for DECIMAL logical type, and serves as container for raw parts of decimal values: unscaled value in bytes, precision and scale.

Variants

[]

Decimal backed by i32.

[]

Fields of Int32

[]

Decimal backed by i64.

[]

Fields of Int64

[]

Decimal backed by byte array.

[]

Fields of Bytes
