rustHow to convert a Rust slice to a fixed array?
To convert a Rust slice to a fixed array, you can use the std::mem::transmute
function. This function takes a slice and converts it to a fixed array of the same size.
Example code
let slice = [1, 2, 3];
let array: [i32; 3] = unsafe { std::mem::transmute(slice) };
Output example
[1, 2, 3]
Code explanation
let slice = [1, 2, 3];
: This line declares a slice of type[i32]
with three elements.let array: [i32; 3]
: This line declares a fixed array of type[i32; 3]
with three elements.unsafe { std::mem::transmute(slice) }
: This line uses thestd::mem::transmute
function to convert the slice to a fixed array.
