Enum NulledResponses

pub enum NulledResponses<T> {
    Repeating(T),
    Sequence(Vec<T>),
}

NulledResponses helps with implementing Configurable Responses for Nullable types.

Variants

Repeating(T)

Repeat a single response forever.

Sequence(Vec<T>)

Return a sequence of responses, panicking when the sequence runs out.

Implementations

impl<T> NulledResponses<T>

pub fn backmap<U>(self, mapper: impl FnMut(T) -> U) -> NulledResponses<U>

Backmap can be used to convert between NulledResponses for different types.

For example, a high-level infrastructure wrapper can use this to convert its own response configuration into a response configuration for an embedded lower-level infrastructure wrapper.

impl<T> NulledResponses<T>

where T: Clone,

pub fn get(&mut self) -> T

Gets the next response.

Panics

Panics if this object was configured with a finite sequence of responses and that sequence has been exhausted.

Trait Implementations
