Crate use_port 

use-port

use-port provides small helpers for parsing port numbers, classifying port ranges, and mapping a few common services to default ports.

Experimental: this crate is below 0.3.0 and the API may change.

Example Usage

use use_port::{common_port_name, parse_port, port_range, PortRange};

let port = parse_port("443").unwrap();

assert_eq!(port.value, 443);
assert_eq!(port_range(port.value), PortRange::System);
assert_eq!(common_port_name(port.value), Some("https"));

Scope

• Port parsing from strings.
• Port range classification.
• Small common service-to-port lookup tables.

Non-goals

• Port scanning.
• Socket binding.
• Service discovery.
