[−][src]Enum parquet::data_type::Decimal
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
Int64
