Struct FmtArgs 

pub struct FmtArgs {
    pub inputs: Vec<PathBuf>,
    pub check: bool,
    pub indent: Option<IndentKind>,
    pub indent_width: Option<u8>,
    pub max_line_width: Option<u32>,
    pub trailing_comma: bool,
    pub no_trailing_comma: bool,
    pub no_config: bool,
}

The fmt subcommand’s flags, shared with bynk fmt the same way (#968): one #[derive(Args)] struct both CLIs flatten, rather than two copies to keep in step as formatting options are added. The fmt subcommand’s arguments, flattened by both bynkc::cli and bynk::cli so the two spell one contract rather than two copies of it (the test_runner::TestArgs pattern, findings #40/#72). Field docs here are the CLI help text for both commands’ flags.

Every style field is an Option, and deliberately carries no clap default_value (#972). The three sources are layered — spec default, then the project’s bynk.toml [fmt], then the flag — and a clap default would make “the user asked for 100” indistinguishable from “the user said nothing”, so a manifest’s max_line_width = 120 would be overwritten by a flag nobody passed. None means defer to the layer below.

Fields

inputs: Vec<PathBuf>

Files to format. Use - for stdin → stdout.

check: bool

Check formatting without writing changes. Exits non-zero if any file is not already canonical.

indent: Option<IndentKind>

Indent with tabs or spaces. Defaults to the project’s [fmt] indent, or tabs.

indent_width: Option<u8>

Spaces per nesting level, with spaces indentation. Defaults to the project’s [fmt] indent_width, or 2. Rejected when the effective indentation is tabs, where it would have no effect.

max_line_width: Option<u32>

Soft target line width in columns. A construct wider than this wraps across lines where the grammar allows; one with no break point in it (a long string literal) is left long. Defaults to the project’s [fmt] max_line_width, or 100.

trailing_comma: bool

Emit a trailing comma in multi-line records, sums, list literals and exports clauses. Overrides a project’s trailing_comma = false, and overrides an earlier --no-trailing-comma.

no_trailing_comma: bool

Omit the trailing comma in multi-line records, sums, list literals and exports clauses. (Parameter and argument lists never carry one — the grammar rejects it — regardless of this flag.)

no_config: bool

Ignore the project’s bynk.toml [fmt] section and format to the canonical style, plus whatever flags this run passes. For a script that wants one fixed rendering whatever project it is pointed at.

Implementations

impl FmtArgs

pub fn apply_to(&self, base: FormatOptions) -> Result<FormatOptions, String>

Layer these arguments over base — the manifest-resolved options for the file about to be formatted — or report why they describe nothing usable. A field the run did not state leaves base untouched.

Trait Implementations

impl Args for FmtArgs

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl Debug for FmtArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromArgMatches for FmtArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<FmtArgs, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<FmtArgs, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.
