Trait Implementations

impl<T> Clone for Maybe<T>

where T: Clone,

fn clone(&self) -> Maybe<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Maybe<T>

where T: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Default for Maybe<T>

fn default() -> Maybe<T>

Returns the “default value” for a type.

impl<'a, T> From<&'a str> for Maybe<T>

where T: From<&'a str>,

fn from(value: &'a str) -> Maybe<T>

Converts to this type from the input type.

impl<D> From<Label<D>> for Maybe<Label<D>>

where D: Dimension,

fn from(value: Label<D>) -> Maybe<Label<D>>

Converts to this type from the input type.

impl<T> GnuCommandFactory for Maybe<T>

where T: GnuCommandFactory,

fn as_commands(&self) -> Result<VecDeque<GnuCommand>, GnuCommandFactoryError>

impl<T> PartialEq for Maybe<T>

where T: PartialEq,

fn eq(&self, other: &Maybe<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Copy for Maybe<T>

where T: Copy,

impl<T> Eq for Maybe<T>

where T: Eq,
