Unwrap or exit with an appropriate error message.

Required Methods§

Source

fn or_exit_e<F>(self, msgf: F) -> T
where F: FnOnce() -> String,

👎Deprecated: This module is in maintenance mode; the anyhow library might be a better choice

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, append an appropriate description of the error, and exit.

where F: FnOnce() -> String,

👎Deprecated: This module is in maintenance mode; the anyhow library might be a better choice

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, append an appropriate description of the error, and exit.
