Trait ArrowPrimitiveType

fn get_byte_width() -> usize { ... }
fn default_value() -> Self::Native { ... }
}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 Constants§
Required Associated Types§
type Native: ArrowNativeTypeOp
type Native: ArrowNativeTypeOp
Corresponding Rust native type for the primitive type.
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().
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
