Implementation

The implementation is in src/operations/typex.rs and declares String input and String output. The operation module owns conversion and domain-error rules; registry resolution, argument validation, input-requirement enforcement, tracing, and output validation are performed by rxchef::execution.

Command-line use

This operation requires input. Supply literal UTF-8 with --input, exact bytes with --input-file, or pipe bytes on stdin.

rxchef run "Typex" --input-file input.bin --output-file output.bin

Arguments may be supplied positionally in the table order or by name with repeatable --arg NAME=VALUE. Omitted optional arguments use the documented defaults.

Pipeline use

Place the operation anywhere a String value is valid. Its String result becomes the next step's input. Compact syntax uses the operation name followed by comma-separated arguments; JSON/YAML recipes use an op field and an args array.

Error conditions

Schema violations are rejected before the operation runs. Malformed input, unsupported parameter combinations, unavailable optional backends, and domain processing failures produce structured errors and a non-zero CLI status; partial output is never reported as success.

CyberChef compatibility

Parity status: Unknown. Unknown records an unassessed compatibility claim; it does not imply equality or incompatibility.

Security considerations

Declared side effects: []. Treat parser inputs as untrusted and apply execution limits to large data. Arguments marked sensitive in the schema are redacted from metadata-aware History displays.

Testing evidence

Differential tests: - tests/tests/differential.rs

Performance classification

Excluded from the committed representative benchmark set: No stable representative benchmark case is defined; operation remains Partial until performance evidence is reviewed.
