[−][src]Trait arrow::datatypes::ArrowPrimitiveType

pub trait ArrowPrimitiveType: 'static {
    type Native: ArrowNativeType;
    fn get_data_type() -> DataType;

    fn get_bit_width() -> usize;

    fn default_value() -> Self::Native;
}

Trait indicating a primitive fixed-width type (bool, ints and floats).

Associated Types

Required methods

fn get_data_type() -> DataType

Returns the corresponding Arrow data type of this primitive type.

fn get_bit_width() -> usize

Returns the bit width of this primitive type.

fn default_value() -> Self::Native

Returns a default value of this primitive type.

This is useful for aggregate array ops like sum(), mean().
