Trait ArrowFloatType 

pub trait ArrowFloatType: Debug {
    type Native: FromPrimitive + FloatToArrayType<ArrowType = Self> + AsPrimitive<f32> + Debug + Display;
    type ArrayType: FloatArray<Self>;

    const FLOAT_TYPE: FloatType;
    const MIN: Self::Native;
    const MAX: Self::Native;

    // Provided method
    fn empty_array() -> Self::ArrayType { ... }
}

Trait for float types used in Lance indexes

This mimics the utilities provided by arrow_array::ArrowPrimitiveType but applies to all float types (including bfloat16)

Required Associated Constants

const FLOAT_TYPE: FloatType

const MIN: Self::Native

const MAX: Self::Native

Required Associated Types

type Native: FromPrimitive + FloatToArrayType<ArrowType = Self> + AsPrimitive<f32> + Debug + Display

type ArrayType: FloatArray<Self>

Arrow Float Array Type.

Provided Methods

fn empty_array() -> Self::ArrayType

Returns empty array of this type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl ArrowFloatType for Float16Type

const FLOAT_TYPE: FloatType = FloatType::Float16

const MIN: Self::Native = f16::MIN

impl ArrowFloatType for Float32Type

const FLOAT_TYPE: FloatType = FloatType::Float32

const MIN: Self::Native = f32::MIN

const MAX: Self::Native = f32::MAX
