rustHow can I order strings in Rust?
Strings in Rust can be ordered using the cmp
method. This method compares two strings and returns an Ordering
enum which can be used to determine the ordering of the strings.
Example code
let string1 = "Hello";
let string2 = "World";
let result = string1.cmp(&string2);
println!("{:?}", result);
Output example
Less
The cmp
method takes a reference to another string as an argument and returns an Ordering
enum which can have one of three values: Less
, Equal
, or Greater
. Less
is returned when the first string is lexicographically less than the second string, Equal
is returned when the strings are equal, and Greater
is returned when the first string is lexicographically greater than the second string.
Code explanation
let string1 = "Hello";
: This line declares a string variable calledstring1
and assigns it the value"Hello"
.let string2 = "World";
: This line declares a string variable calledstring2
and assigns it the value"World"
.let result = string1.cmp(&string2);
: This line calls thecmp
method onstring1
and passes a reference tostring2
as an argument. The result of thecmp
method is stored in theresult
variable.println!("{:?}", result);
: This line prints the value of theresult
variable to the console.
