Function array_tools::init_with_slice [−][src]
pub fn init_with_slice<T, A>(slice: &[T]) -> Option<A> where
A: FixedSizeArray<T>,
T: Clone,
Attempts to initialize array of T
with slice of T
([T]
).
- If slice length is less than array length, this function returns
None
. - If slice length is greater or equal to array length, this function returns
Some(array)
.
This function clones slice elements.
Examples
Not enough elements case.
use array_tools as art; let slice = &[1i32, 2, 3, 4, 5, 6]; let result: Option<[i32; 8]> = art::init_with_slice(slice); assert_eq!(result, None); let slice = &[1i32, 2, 3, 4, 5, 6]; let result: Option<[i32; 4]> = art::init_with_slice(slice); assert_eq!(result, Some([1i32, 2, 3, 4]));
