rustHow do I get the first character from a string in Rust?
The easiest way to get the first character from a string in Rust is to use the chars()
method. This method returns an iterator over the characters of a string. The first character can then be accessed using the next()
method.
Example code
let s = "Hello";
let first_char = s.chars().next();
Output example
Some('H')
Code explanation
let s = "Hello"
: This line declares a string variables
and assigns it the value"Hello"
.let first_char = s.chars().next()
: This line calls thechars()
method on thes
string variable, which returns an iterator over the characters of the string. Thenext()
method is then called on the iterator, which returns the first character of the string.
