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_sliceof typeVec<i32>, which is a slice of typei32. -
Vec::new()- This creates an empty slice of typei32.
For more information, see the Rust documentation.
