Struct ParsePartitionFaceError 

#[non_exhaustive]
pub struct ParsePartitionFaceError {
    pub label: String,
}

Typed parse failure of [<PartitionFace as std::str::FromStr>::from_str] — the offending input was not a canonical name on the PartitionFace surface.

The two-variant face axis carries a small closed label set ("realizable", "unrealizable"), so the parser’s single rejection mode is “input did not match any canonical name”. This struct carries the offending substring verbatim in the label field so a downstream consumer can localize the failure to the surrounding context (a YAML attestation manifest field, a structured-log face-keyed scalar, a CLI argument).

#[non_exhaustive] so a future stricter parse rule (e.g. an EmptyInput distinguished from UnknownLabel) lands as a new variant without a SemVer-major bump. Idiom-peer of ParseModalityClassError, ParseSupportCardinalityClassError, ParseSupportBoundaryDistanceError, and ParseSupportMagnitudeDirectionError on the four typed-cube-classifier surfaces.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

label: String

The offending input substring, verbatim.
