Enum MaybeEmpty 

pub enum MaybeEmpty<T> {
    Some(T),
    None,
}

Deserializer of empty string values into optionals.

Variants

Some(T)

Some.

None

None.

Trait Implementations

impl<T: Clone> Clone for MaybeEmpty<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for MaybeEmpty<T>

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

Formats the value using the given formatter.

impl Default for MaybeEmpty<Uint>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, T> Deserialize<'a> for MaybeEmpty<T>

where T: Deserialize<'a>,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl From<MaybeEmpty<Uint>> for U256

fn from(maybe: MaybeEmpty<Uint>) -> U256

Converts to this type from the input type.

impl From<MaybeEmpty<Uint>> for u64

fn from(maybe: MaybeEmpty<Uint>) -> u64

Converts to this type from the input type.

impl<T> Into<Option<T>> for MaybeEmpty<T>

fn into(self) -> Option<T>

Converts this type into the (usually inferred) input type.

impl<T: PartialEq> PartialEq for MaybeEmpty<T>

fn eq(&self, other: &MaybeEmpty<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.
