Enum StreamGraphBuildError 

#[non_exhaustive]
pub enum StreamGraphBuildError {
    UnsupportedChainLength,
    ZeroCapacity,
    EmptyRecordDomain,
}

Invalid stream-graph configuration.

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.

UnsupportedChainLength

Only three- and four-stage chains are currently represented.

ZeroCapacity

Every inter-stage queue needs positive capacity.

EmptyRecordDomain

The record value domain must be nonempty.
