[−][src]Trait az::Az
Used to cast values.
This is a convenience trait to enable writing src.az::<Dst>()
. This
would not work with the Cast::cast
method because the Cast
trait is generic while the cast
method
is not generic.
This trait’s method is suitable for chaining.
Panics
When debug assertions are enabled, this trait’s method panics if the
value does not fit in the destination. When debug assertions are not
enabled (usual in release mode), the wrapped value can be returned,
but it is not considered a breaking change if in the future it panics;
if wrapping is required use WrappingAs
instead.
This trait’s method also panics with no debug assertions if the value does not fit and cannot be wrapped, for example when trying to cast floating-point ∞ into an integer type.
Examples
use az::Az; assert_eq!(5i32.az::<u32>(), 5); assert_eq!(17.1f32.az::<u8>(), 17);
