rustDoes Rust perform bounds checking on slices?
Yes, Rust performs bounds checking on slices. This is done to ensure that the slice does not exceed the length of the underlying array.
For example, the following code will cause a panic due to an out-of-bounds access:
let arr = [1, 2, 3];
let slice = &arr[..4];
Output example
thread 'main' panicked at 'index out of bounds: the len is 3 but the index is 4', src/libcore/slice/mod.rs:2706:10
The code above attempts to create a slice of arr
from index 0 to index 4, which is out of bounds since arr
only has 3 elements.
