}Expand description
Trait bridging the dynamic-typed nature of Arrow (via DataType) with the
static-typed nature of rust types (ArrowNativeType) for all types that implement ArrowNativeType.
Associated Types
type Native: ArrowNativeType
type Native: ArrowNativeType
Corresponding Rust native type for the primitive type.
Associated Constants
Provided methods
fn get_byte_width() -> usize
fn get_byte_width() -> usize
Returns the byte width of this primitive type.
fn default_value() -> Self::Native
fn default_value() -> Self::Native
Returns a default value of this primitive type.
This is useful for aggregate array ops like sum(), mean().
