Enum optics::concrete::ErrorCompose

pub enum ErrorCompose<E, S, R> {
    Head(E),
    Tail(S, R),
}

Error type for Composed optics.

Variants

Head(E)

Error happened for the first optics in this composition.

Tail(S, R)

Operation for the first optics succeeded in this composition.

Trait Implementations

impl<E: Clone, S: Clone, R: Clone> Clone for ErrorCompose<E, S, R>

fn clone(&self) -> ErrorCompose<E, S, R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug, S: Debug, R: Debug> Debug for ErrorCompose<E, S, R>

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

Formats the value using the given formatter.

impl<E: Display, S: Display, R: Display> Display for ErrorCompose<E, S, R>

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

Formats the value using the given formatter.

impl<E, S, R> From<E> for ErrorCompose<E, S, R>

fn from(err: E) -> Self

Converts to this type from the input type.

impl<E: PartialEq, S: PartialEq, R: PartialEq> PartialEq for ErrorCompose<E, S, R>

fn eq(&self, other: &ErrorCompose<E, S, R>) -> 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.
