}Expand description
Trait for [ArrowNativeType] that adds checked and unchecked arithmetic operations,
and totally ordered comparison operations
The APIs with _wrapping suffix do not perform overflow-checking. For integer
types they will wrap around the boundary of the type. For floating point types they
will overflow to INF or -INF preserving the expected sign value
Note div_wrapping and mod_wrapping will panic for integer types if rhs is zero
although this may be subject to change https://github.com/apache/arrow-rs/issues/2647
The APIs with _checked suffix perform overflow-checking. For integer types
these will return Err instead of wrapping. For floating point types they will
overflow to INF or -INF preserving the expected sign value
Comparison of integer types is as per normal integer comparison rules, floating
point values are compared as per IEEE 754’s totalOrder predicate see f32::total_cmp
Required Associated Constants§
Sourceconst MIN_TOTAL_ORDER: Self
const MIN_TOTAL_ORDER: Self
The minimum value and identity for the max aggregation.
Note that the aggregation uses the total order predicate for floating point values,
which means that this value is a negative NaN.
Sourceconst MAX_TOTAL_ORDER: Self
const MAX_TOTAL_ORDER: Self
The maximum value and identity for the min aggregation.
Note that the aggregation uses the total order predicate for floating point values,
which means that this value is a positive NaN.

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.
