Struct ArgsSpec 

pub struct ArgsSpec {
    pub options: Vec<OptionDecl>,
    pub positionals: Vec<PositionalDecl>,
    pub lenient_unknowns: bool,
}

Declarative spec of what flags and positionals a CLI accepts. Built by the #[derive(FdlArgs)] output at runtime, consumed by parse.

Fields

options: Vec<OptionDecl>

positionals: Vec<PositionalDecl>

lenient_unknowns: bool

When true, unknown long/short flags are silently skipped (the token is consumed, no error is raised), and the required- positional check is disabled. Used by fdl’s non-strict tail validation: the binary re-parses the argv itself, so fdl’s job is to enforce declared contracts (choices on known flags, positional choices when unambiguous) without blocking pass-through flags the author chose to allow.

Defaults to false so derive binaries stay strict by default.
