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 variable my_slice
  • Vec::with_capacity(10): creates a Rust slice with a capacity of 10 elements
