rustHow to create a Rust slice with a specific size?
A Rust slice is a data structure that allows access to a contiguous sequence of elements in memory. To create a Rust slice with a specific size, you can use the std::vec::Vec::with_capacity
method. This method takes a single argument, which is the size of the slice.
let mut my_slice = Vec::with_capacity(10);
This code creates a Rust slice with a capacity of 10 elements.
Code explanation
let mut my_slice
: declares a mutable variablemy_slice
Vec::with_capacity(10)
: creates a Rust slice with a capacity of 10 elements
