}

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

Int32

Decimal backed by i32.

Fields of Int32

value: [u8; 4]precision: i32scale: i32
Int64

Decimal backed by i64.

Fields of Int64

value: [u8; 8]precision: i32scale: i32
Bytes

Decimal backed by byte array.

Fields of Bytes

value: Vec<u8>precision: i32scale: i32

Implementations

impl Decimal[src]

pub fn from_bytes(value: Vec<u8>, precision: i32, scale: i32) -> Decimal[src]
