Struct Param 

pub struct Param { /* private fields */ }

One parameter the document declares.

Everything that only a parameter with a flag has — the flag, where its value goes, what the flag accepts — hangs off Shape, because a parameter this CLI cannot spell has none of it.

Implementations

impl Param

pub fn name(&self) -> &str

The wire name, as the document spells it.

pub fn shape(&self) -> &Shape

What this parameter is worth on a command line: a flag and everything that goes with one, or nothing.

pub fn required(&self) -> bool

pub fn description(&self) -> Option<&str>
