Trait OkOrNotFound 

pub trait OkOrNotFound {
    type T;

    // Required method
    fn ok_or_not_found<B>(self) -> Result<Self::T, NotFoundError<B>>;
}

An extension trait for Option<T> to convert it to Result<T, NotFoundError<AnotherType>>

Useful in places where you need NotFoundError<AnotherType> instead of NotFoundError<T>.

Examples

pub fn get_root(path: &Path) -> Result<&Path, NotFoundError<WorkspaceRoot>> {
     find_root(path).ok_or_not_found()
}
