A physical native representation of a Parquet fixed-sized type.

Required Associated Constants

const TYPE: PhysicalType

Required Associated Types

type Bytes: AsRef<[u8]> + Pod + IntoIterator<Item = u8> + for<'a> TryFrom<&'a [u8], Error = TryFromSliceError> + Debug + Clone + Copy

Required Methods

fn to_le_bytes(&self) -> Self::Bytes

fn from_le_bytes(bytes: Self::Bytes) -> Self

fn ord(&self, other: &Self) -> Ordering

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
