Struct CommandTree 

pub struct CommandTree<'a> { /* private fields */ }

A traversable view of the command tree in a schema.

CommandTree provides a unified API for iterating over commands, filtering by type (leaf vs parent), and accessing command metadata.

Implementations

impl<'a> CommandTree<'a>

pub fn new(schema: &'a Manifest) -> Self

Create a new CommandTree from a schema.

pub fn iter(&self) -> impl Iterator<Item = &FlatCommand<'a>>

Iterate over all commands in depth-first order.

pub fn leaves(&self) -> impl Iterator<Item = &FlatCommand<'a>>

Iterate over leaf commands only (commands without subcommands).

These are the commands that have handlers.

pub fn parents(&self) -> impl Iterator<Item = &FlatCommand<'a>>

Iterate over parent commands only (commands with subcommands).

These are command groups that contain other commands.

pub fn len(&self) -> usize

Get the total number of commands.

pub fn is_empty(&self) -> bool

Check if the tree is empty.

pub fn leaf_count(&self) -> usize

Get the number of leaf commands.

pub fn parent_count(&self) -> usize

Get the number of parent commands.

pub fn to_vec(&self) -> Vec<FlatCommand<'a>>

Convert to a Vec of all commands.

pub fn collect_paths(&self) -> HashSet<String>

Collect all command paths as strings.

Returns a set of path strings like “db/migrate”, “hello”.

pub fn collect_leaf_paths(&self) -> HashSet<String>

Collect only leaf command paths (commands without subcommands).

These are the paths that correspond to actual handler files.

pub fn display(&'a self) -> CommandTreeDisplay<'a>

Create a display formatter with default settings.

pub fn display_style(&'a self, style: DisplayStyle) -> CommandTreeDisplay<'a>

Create a display formatter with a specific style.

Trait Implementations

impl<'a> Clone for CommandTree<'a>

fn clone(&self) -> CommandTree<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for CommandTree<'a>

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

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a CommandTree<'a>

type Item = &'a FlatCommand<'a>

The type of the elements being iterated over.

type IntoIter = Iter<'a, FlatCommand<'a>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for CommandTree<'a>

type Item = FlatCommand<'a>

The type of the elements being iterated over.

type IntoIter = IntoIter<FlatCommand<'a>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
