Enum agnes::masked::MaybeNa

pub enum MaybeNa<T: DataType> {
    Na,
    Exists(T),
}

Missing value container.

Variants

Na

Indicates a missing (NA) value.

Exists(T)

Indicates an existing value.

Methods

impl<T: DataType> MaybeNa<T>

pub fn unwrap(self) -> T

Unwrap a MaybeNa, revealing the data contained within. Panics if called on an Na value.

pub fn exists(&self) -> bool

Test if a MaybeNa contains a value.

pub fn is_na(&self) -> bool

Test if a MaybeNa is NA.

pub fn as_ref<'a>(&'a self) -> MaybeNa<&'a T>

Returns a MaybeNa which contains a reference to the original underlying datum.

pub fn map<U: DataType, F: FnMut(T) -> U>(self, f: F) -> MaybeNa<U>

Applies function f if this MaybeNa exists.

impl<'a, T: DataType + Clone> MaybeNa<&'a T>

pub fn cloned(self) -> MaybeNa<T>

Create a owner MaybeNa out of a reference-holding MaybeNa using clone().
