Simple clamping of numbers in Rust
clamped
relies heavily on conditional compilation with Cargo's feature system.
You need to enable all the elements of clamped
you need via features.
You can enable each feature independently (they won't conflict with each other).
The current features are
clamp_trait
: theClamp
trait and it's correspondingclamped
member function
use clamped::Clamp;
// Clamp numbers between 20 and 30
assert_eq!(10.clamped(20, 30), 20); // 10 -> 20
assert_eq!(15.clamped(20, 30), 20); // 15 -> 20
assert_eq!(20.clamped(20, 30), 20); // 20 -> 20
assert_eq!(25.clamped(20, 30), 25); // 25 -> 25
assert_eq!(30.clamped(20, 30), 30); // 30 -> 30
assert_eq!(35.clamped(20, 30), 30); // 35 -> 30
-
clamp_fn
: Theclamp
function, which is the same as theClamp
+clamped
method, but does not use a trait method -
clamp_macro
: Aclamp!
macro, which contains the signature of all clamp functions. You can use this if you don't want to include any more traits, functions, or other external code. -
inline_always
: This feature modifies the signature of all functions in the crate, turning on the#[inline(always)]
attribute. This will force the compiler to inline all calls, essentially allowing functions and trait methods to act like macros with type checking.
Note: Only the clamp_trait
feature is enabled by default (This may change in the future as more features are added)
All features are currently #[no_std]
compatible, but this may change in the future!!!
