Struct SubcommandRouter 

pub struct SubcommandRouter { /* private fields */ }

Strategy helper implementing chain-of-responsibility style subcommand dispatch.

The router handles the first token of args as the subcommand name and forwards trailing arguments recursively to the selected child strategy.

Implementations

impl SubcommandRouter

pub fn new() -> Self

Creates an empty router.

pub fn register(self, command: Command) -> Self

Registers a subcommand and returns self for chaining.

pub fn register_mut(&mut self, command: Command) -> &mut Self

Registers a subcommand in-place.

Trait Implementations

impl CommandStrategy for SubcommandRouter

fn execute( &self, _options: Vec<Switch>, _arguments: Vec<Argument>, params: Vec<String>, ) -> Result<(), StrategyError>

Executes the strategy with parsed invocation data. Strategy implementations should validate argument viability internally.

fn subcommand_catalog(&self) -> Option<&dyn SubcommandCatalog>

Optional catalog exposure used by help renderers to discover nested command trees.

impl Default for SubcommandRouter

fn default() -> SubcommandRouter

Returns the “default value” for a type.

impl SubcommandCatalog for SubcommandRouter

fn subcommands(&self) -> Vec<Command>

Returns direct subcommands owned by this strategy.
