[−][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

`type Native: ArrowNativeType`

Corresponding Rust native type for the primitive type.

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().
