Trait OptionExt 

pub trait OptionExt<T> {
    // Required methods
    fn or_exit(self) -> T;
    fn _elog(self, _: &str) -> T;
    fn elog<E: Display>(self, _: E) -> Result<T, E>;
    fn wlog<E: Display>(self, _: E) -> Result<T, E>;
}

Required Methods

fn or_exit(self) -> T

Unwrap or exit

fn _elog(self, _: &str) -> T

Unwrap or log and exit

fn elog<E: Display>(self, _: E) -> Result<T, E>

Log the error if None, then transform to a Result.

fn wlog<E: Display>(self, _: E) -> Result<T, E>

Log the error as a warning if None, then transform to a Result.

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.
