pub struct ExitCode(_);
This type represents the status code a process can return to its parent under normal termination.
Numeric values used in this type don't have portable meanings, and different platforms may mask different amounts of them.
For the platform's canonical successful and unsuccessful codes, see the SUCCESS and FAILURE associated items.
Warning: While various forms of this were discussed in RFC #1937, it was ultimately cut from that RFC, and thus this type is more subject to change even than the usual unstable item churn.
impl ExitCode[src]
pub const SUCCESS: ExitCode[src]
The canonical ExitCode for successful termination on this platform.
Note that a ()-returning main implicitly results in a successful termination, so there's no need to return this from main unless you're also returning other possible codes.
pub const FAILURE: ExitCode[src]
The canonical ExitCode for unsuccessful termination on this platform.
If you're only returning this and SUCCESS from main, consider instead returning Err(_) and Ok(()) respectively, which will return the same codes (but will also eprintln! the error).
