Trait OptionFault

pub trait OptionFault<T> {
    // Required methods
    fn ok_or_fault(self) -> Result<T, Fault>;
    fn ok_or_fault_force(self) -> Result<T, Fault>;
}

To use this trait on Option import the prelude use explicit_error::prelude::*

Required Methods

fn ok_or_fault(self) -> Result<T, Fault>

Transforms the Option<T> into a Result<T, Fault>, mapping Some(v) to Ok(v) and None to Err(Fault)

fn foo() -> Result<(), Error> {
    let option: Option<u8> = None;
    option.ok_or_fault().with_context("Help debugging")?;
}

fn ok_or_fault_force(self) -> Result<T, Fault>

Transforms the Option<T> into a Result<T, Fault>, mapping Some(v) to Ok(v) and None to Err(Fault) forcing backtrace capture

fn foo() -> Result<(), Error> {
    let option: Option<u8> = None;
    option.ok_or_fault_force().with_context("Help debugging")?;
}
