Crate cabin_fmt 

clang-format runner used by Cabin’s developer-tools commands.

This crate keeps formatting-specific executable resolution, command-line construction, and exit-status handling outside cabin, mirroring the crate boundaries used by cabin-tidy.

Crate boundaries:

• the crate owns formatter executable resolution and the clang-format command-line shape;
• it accepts typed inputs (FormatRequest) and emits typed outcomes (FormatReport);
• it never walks the filesystem looking for sources — that job belongs to cabin-source-discovery;
• it never reads Cabin’s configuration files — the orchestration layer threads any config-derived inputs through the typed FormatRequest.

Structs

FormatRequest

Input for run_formatter.

Enums

ExitStatusKind

Exit-status classification, shared with cabin-tidy so the two external-tool runners report process outcomes the same way. Stringified exit-status kind preserved so the orchestration layer can decide whether to display an exit code or a signal.

FormatError

Errors surfaced by the runner.

FormatMode

Operation mode the runner should perform.

FormatReport

Per-mode outcome of run_formatter.

Functions

resolve_formatter_executable

Resolve the formatter executable Cabin should spawn.

run_formatter

Run clang-format over the requested files.
