Module cli 

Command-line interface — a thin shell over the tzcompile library.

The CLI parses arguments, builds a CompileConfig, and calls the library. It holds no compiler logic of its own; everything substantive lives in the library so it can be reused and tested directly. Subcommands:

• compile — compile selected zones to a TZif tree under --out;
• compare — compile a zone and diff it against reference zic (the oracle);
• explain — say what a zone would compile to, or why it is unsupported;
• supported-syntax — print the subset this version implements;
• support-report — map a whole source file: which identifiers compile, and why the rest don’t.

Structs

AuxTableValidateArgs

aux-table-validate (T16.4): structural validation of auxiliary .tab files. Each flag points at a table file directly — they are not --input compile sources (the category law).

Cli

Top-level CLI definition.

CompareArgs

CompileArgs

DoctorArgs

doctor (T16.6b): read-only environment probe.

ExplainArgs

ReleaseDiffArgs

release-diff (T16.6a): diff two tzdb releases per identifier.

SemanticReportArgs

semantic-report (T15.3): typed zdump-backed semantic witnesses for a compact zone set.

SizeReportArgs

StructuralReportArgs

SupportReportArgs

TzifValidateArgs

tzif-validate (T15.4): RFC 9636 structural validation of zic-rs + reference TZif output.

VendorOracleAdmitArgs

vendor-oracle-admit (T16.5b): ingest + admit an external receipt JSON file.

Enums

BloatArg

Reference zic’s -b {slim|fat} bloat value (T10.2). This is the emission policy knob — whether otherwise-redundant transitions are kept (fat) or dropped (slim) — and is a thin alias onto EmitStyleArg. It is not the TZif version (content-driven) and not the -R redundant-tail range. zic’s own default is slim; zic-rs keeps a behaviour-matched fat-style default and only changes emission when asked.

Command

CompareModeArg

--mode value.

EmitStyleArg

--emit-style value (T8-slim).

LinkModeArg

--link-mode value.

ReportFormatArg

--format value for support-report.

UnsupportedArg

--unsupported value.

Functions

run

Run the CLI. Returns Ok(()) on success; the caller maps Err to a process exit code.

supported_syntax_text

The human-readable supported-syntax summary (also the source of truth for docs/supported-syntax.md’s prose).
