Trait Implementations

impl<T: Clone, E: Clone> Clone for ValueResult<T, E>

fn clone(&self) -> ValueResult<T, E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, E: Debug> Debug for ValueResult<T, E>

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

Formats the value using the given formatter.

impl<T: Default, E> Default for ValueResult<T, E>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Default, E> From<Result<T, E>> for ValueResult<T, E>

fn from(result: Result<T, E>) -> Self

Converts to this type from the input type.

impl<T: PartialEq, E: PartialEq> PartialEq for ValueResult<T, E>

fn eq(&self, other: &ValueResult<T, E>) -> 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.
