To make a character uppercase in Rust, you can use the to_ascii_uppercase
method provided by the standard library. This method converts the character to its uppercase equivalent if it has one. Here is an example demonstrating how to make a character uppercase in Rust:
1 2 3 4 |
let lower_char = 'a'; let upper_char = lower_char.to_ascii_uppercase(); println!("Uppercase char: {}", upper_char); |
In this example, the character 'a' is converted to its uppercase equivalent 'A' using the to_ascii_uppercase
method. You can use this method to convert any character to uppercase in Rust.
How to capitalize a char in Rust using standard libraries?
To capitalize a character in Rust using standard libraries, you can use the to_ascii_uppercase
method provided by the char
type. Here is an example of how you can capitalize a character:
1 2 3 4 5 6 |
fn main() { let c = 'a'; let capitalized_char = c.to_ascii_uppercase(); println!("{}", capitalized_char); } |
In this example, the to_ascii_uppercase
method is called on the character c
, which converts it to its uppercase equivalent ('A' in this case). The capitalized character is then printed to the console.
How to convert a character to uppercase in Rust?
You can convert a character to uppercase in Rust by using the to_ascii_uppercase
method provided by the standard library. Here's an example of how to convert a character to uppercase:

fn main() { let lowercase_char = 'a'; let uppercase_char = lowercase_char.to_ascii_uppercase(); println!("{}", uppercase_char); } |
In this example, the character 'a' is converted to uppercase using the to_ascii_uppercase
method, and the result is printed to the console. This will output:
1

How to change a single char to uppercase in Rust?
You can change a single character to uppercase in Rust by converting the character to a String, changing it to uppercase, and then converting it back to a character. Here is an example code snippet:
1 2 3 4 5 6 |
fn main() { let mut c = 'a'; let upper = c.to_string().to_uppercase(); c = upper.chars().nth(0).unwrap(); println!("{}", c); } |
This code snippet converts the character 'a' to uppercase and then prints the result. You can change the value of the c
variable to any character you want to convert to uppercase.
