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

Unwrap or exit with the specified message.

Required Methods

fn or_exit<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, and exit.

fn or_die<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, do not unwind the stack, call the supplied function to obtain an error message, display it, and exit.

Provided Methods

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

👎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, display the specified message, and exit.

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

👎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, display the specified message, and exit.

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

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

Alias for Expected::or_die_.

fn expect_or_die<F>(self, msgf: F) -> T

where F: FnOnce() -> String,

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

Alias for Expected::or_die.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
