Struct Namespace 

pub struct Namespace(/* private fields */);

The flag names one subcommand has already spent.

Requires the document feature.

PUT /vouchers/{id} takes an id in the path and an id in the body; clap panics on a duplicate name, so the second claimant is prefixed rather than dropped. Both values stay reachable from the command line, and the flag that moved says which wire name it carries in its help line — renamed is how a flag reports that once the document it came from is gone.

Implementations

impl Namespace

pub fn with_reserved<const N: usize>(reserved: [&str; N]) -> Self

Start with the CLI’s own flags already spent, so a document that happens to name a field commit renames rather than colliding at startup.

pub fn claim(&mut self, preferred: &str, prefix: &str) -> String

The flag to use: preferred when it is free, otherwise prefixed.

Trait Implementations

impl Debug for Namespace

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

Formats the value using the given formatter.
