rustHow to create an empty slice in Rust?
Creating an empty slice in Rust is easy. You can use the Vec::new()
method to create an empty slice. The following example code creates an empty slice of type i32
:
let empty_slice: Vec<i32> = Vec::new();
The output of the above code is an empty slice:
[]
The code consists of two parts:
-
let empty_slice: Vec<i32>
- This declares a variableempty_slice
of typeVec<i32>
, which is a slice of typei32
. -
Vec::new()
- This creates an empty slice of typei32
.
