Struct Args 

pub struct Args {
    pub scene: String,
    pub list_scenes: bool,
    pub size: Option<(u32, u32)>,
    pub mcp: bool,
}

Every option the example accepts.

Fields

scene: String

the scene to start from

list_scenes: bool

print the scene table and exit

size: Option<(u32, u32)>

initial window size in pixels, as WxH; the scene’s own when omitted

mcp: bool

serve the scene over the Model Context Protocol on standard input and output, showing the frames it renders in the window

Implementations

impl Args

fn validate(&self) -> Result<(), String>

The checks that span more than one option.

argh has already parsed each option on its own; this is the part only the combination can decide.

Trait Implementations

impl Clone for Args

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Args

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

Formats the value using the given formatter.

impl Default for Args

fn default() -> Self

Returns the “default value” for a type.

impl FromArgs for Args

fn from_args(__cmd_name: &[&str], __args: &[&str]) -> Result<Self, EarlyExit>

Construct the type from an input set of arguments.

fn redact_arg_values( __cmd_name: &[&str], __args: &[&str], ) -> Result<Vec<String>, EarlyExit>

Get a String with just the argument names, e.g., options, flags, subcommands, etc, but without the values of the options and arguments. This can be useful as a means to capture anonymous usage statistics without revealing the content entered by the end user.

impl PartialEq for Args

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for Args

impl TopLevelCommand for Args
