Struct sounding_base::missing_value::OptionVal

pub struct OptionVal<T: PartialEq + Copy + MissingData<T>> { /* fields omitted */ }

A newtype to wrap a type and implement the MissingData trait.

Methods

impl<T> OptionVal<T> where
    T: PartialEq + Copy + MissingData<T>, 

fn as_option(self) -> Option<T>

Convert it to an option. The into trait should cover this, but the compiler has troubles inferring the type, so this function is provided. The Into trait is still useful in contexts where the compiler can infer the type correctly, like the body of this function.

fn unwrap(self) -> T

Despite its name, this method does not panic, it just returns the interior value even if that value is the 'Missing Data' flag value.
