Trait Implementations

impl<T: Clone> Clone for OptDatum<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for OptDatum<T>

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

Formats the value using the given formatter.

impl<T, E> Deser for OptDatum<T>

where T: TryFrom<Datum, Error = E>, E: Into<Error>,

fn skip<R: Read + Seek>(r: &mut R) -> Result<ReadResult<()>>

fn deser<R: Read + Seek>(r: &mut R) -> Result<ReadResult<Self>>

fn deser_solo(buf: &[u8]) -> Result<Self>

impl From<&OptDatum<Datum>> for DatumType

fn from(optdat: &OptDatum<Datum>) -> Self

Converts to this type from the input type.

impl<T> From<OptDatum<T>> for Option<T>

fn from(optdat: OptDatum<T>) -> Option<T>

Converts to this type from the input type.

impl<T> From<Option<T>> for OptDatum<T>

fn from(opt: Option<T>) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for OptDatum<T>

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

This method tests for self and other values to be equal, and is used by ==.

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

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