rustHow to convert a slice of characters to a string in Rust?


To convert a slice of characters to a string in Rust, you can use the String::from function. This function takes a &str as an argument and returns a String type.

Example code

let chars = ['h', 'e', 'l', 'l', 'o'];
let string = String::from(&chars[..]);

Output example

hello

The code above creates a slice of characters chars and then uses the String::from function to convert it to a String type. The & before the chars indicates that the function takes a reference to the slice.

Code explanation

  • let chars = ['h', 'e', 'l', 'l', 'o'];: This creates a slice of characters.
  • let string = String::from(&chars[..]);: This uses the String::from function to convert the slice of characters to a String type. The & before the chars indicates that the function takes a reference to the slice.
