Struct Directive 

pub struct Directive {
    pub cli_flag: &'static str,
    pub yaml_directive: &'static str,
    pub yaml_form: YamlForm,
    pub applies_to: KindMask,
    pub target: DirectiveTarget,
    pub value: ValueProvider,
    pub repeatable: bool,
}

One directive: its CLI flag, its YAML directive name, the kinds it applies to, and the value-space it consumes.

cli_flag is always --<name>. yaml_directive is the keyword the YAML parser recognises; for some directives the YAML form is <name> <value> (no =) and for others it’s <name>=<value>. [yaml_form] captures that.

Fields

cli_flag: &'static str

CLI long flag (e.g. --over, --palette).

yaml_directive: &'static str

YAML directive keyword (e.g. over, palette).

yaml_form: YamlForm

Whether the YAML form uses = or whitespace between keyword and value.

applies_to: KindMask

Kinds the directive applies to. Per-item declarations on a non-applicable kind warn at parse time (SRD-46 §“Style and metadata directives”).

target: DirectiveTarget

Where the directive’s value lands in the AST.

value: ValueProvider

Value-space for completion + parser validation.

repeatable: bool

Whether the flag may appear more than once in one command-line invocation (e.g. --series is repeatable; --label is not).
