}Expand description
Trait for primitive values.
This trait bridges the dynamic-typed nature of Arrow
(via DataType) with the static-typed nature of rust types
(ArrowNativeType) for all types that implement ArrowNativeType.
Required Associated Types§
sourcetype Native: ArrowNativeTypeOp
type Native: ArrowNativeTypeOp
Corresponding Rust native type for the primitive type.
Required Associated Constants§
Provided Methods§
sourcefn get_byte_width() -> usize
👎Deprecated: Use ArrowNativeType::get_byte_width
fn get_byte_width() -> usize
Returns the byte width of this primitive type.
sourcefn 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().
Object Safety§
This trait is not object safe.
