Expand description

Unwrap or exit with the specified message.

Required methods

[src]

fn or_exit_(self, msg: &str) -> T

Test the value. On success, return the unwrapped value. On error, unwind the stack, display the specified message, and exit.

[src]

fn or_exit<F>(self, f: F) -> T where
F: FnOnce() -> String,

Test the value. On success, return the unwrapped value. On error, unwind the stack, call the supplied function to obtain an error message, display it, and exit.

[src]

fn or_die_(self, msg: &str) -> T

Test the value. On success, return the unwrapped value. On error, do not unwind the stack, display the specified message, and exit.

[src]

fn or_die<F>(self, f: F) -> T where
F: FnOnce() -> String,

Test the value. On success, return the unwrapped value. On error, do not unwind the stack, call the supplied function to obtain an error message, display it, and exit.
