Available on crate features std or alloc only.

Constructs NonEmptyVec<T> containing the provided arguments.

Examples

Providing no arguments results in compile-time errors:

use non_empty_slice::non_empty_vec;

let never = non_empty_vec![];

Providing one argument:

use non_empty_slice::non_empty_vec;

let single = non_empty_vec![13];

Providing argument implementing Clone and non-zero count of type Size:

use non_empty_slice::non_empty_vec;
use non_zero_size::const_size;

let repeated = non_empty_vec![13; const_size!(42)];

Equivalently, one can use:

use non_empty_slice::non_empty_vec;

let repeated = non_empty_vec![13; const 42];

Passing zero will cause compilation to fail:

use non_empty_slice::non_empty_vec;

let never = non_empty_vec![13; const 0];

Instead of something like this:

use non_empty_slice::non_empty_vec;
use non_zero_size::size;

let repeated = non_empty_vec![13; size!(42)];

It is possible to use this instead:

use non_empty_slice::non_empty_vec;

let repeated = non_empty_vec![13; run 42];

Passing zero will cause panics:

use non_empty_slice::non_empty_vec;

let never = non_empty_vec![13; run 0];

Finally, providing multiple arguments:

use non_empty_slice::non_empty_vec;

let nice = non_empty_vec![13, 42, 69];
