Resolved stage callable.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MapOk(fn(&[u8], &mut [u8]) -> usize)

Infallible map.

Map(fn(&[u8], &mut [u8]) -> Result<usize, Box<dyn Error + Send + Sync>>)

Fallible map.

Filter(fn(&[u8]) -> Result<bool, Box<dyn Error + Send + Sync>>)

Fallible filter.

Inspect(fn(&[u8]) -> Result<(), Box<dyn Error + Send + Sync>>)

Fallible inspect.

Stateful(Box<dyn StatefulStage + Send>)

Stateful stage implementation (explicit opt-in).

StatefulTransform(Box<dyn StatefulTransformStage + Send>)

Stateful transform stage implementation (explicit opt-in).
