Typedefs

AsyncMapCallback<V> = FutureOr<V> Function(V value)

A callback that has a right or left argument and returns that same async argument.

AsyncMaybeCallback<T> = FutureOr<T> Function()

A callback that has no arguments and returns the async result of the orElse function.

AsyncWhenCallback<T, V> = FutureOr<T> Function(V value)

A callback that takes a right or left value argument and returns the async result of a function.

EitherCallback<V> = void Function(V value)

A callback that has a right or left value argument and returns nothing.

LazyCallback<T> = T Function()

Lazy callback

MapCallback<V> = V Function(V value)

A callback that has a right or left argument and returns that same argument.

MaybeCallback<T> = T Function()

A callback that has no arguments and returns the result of the orElse function.

WhenCallback<T, V> = T Function(V value)
