Struct Path 

pub struct Path<'a, const MAX_DEPTH: usize> { /* private fields */ }

Unix-style path parser and representation.

Handles absolute and relative paths with . and .. navigation. Zero-allocation parsing using string slices.

Path Syntax

• Absolute paths: Start with / (e.g., /system/reboot)
• Relative paths: No leading / (e.g., network/status, ../hw)
• Parent navigation: .. goes up one level
• Current directory: . stays at current level

Memory

Uses MAX_DEPTH const generic to limit nesting depth. All parsing is zero-allocation, working with string slices.

Implementations

impl<'a, const MAX_DEPTH: usize> Path<'a, MAX_DEPTH>

pub fn parse(input: &'a str) -> Result<Self, CliError>

Parse path string into Path structure.

Supports absolute (/system/reboot), relative (cmd, ./cmd), and parent (..) paths.

Returns InvalidPath for empty input or PathTooDeep if MAX_DEPTH exceeded.

pub fn is_absolute(&self) -> bool

Returns true if this is an absolute path (starts with /).

pub fn segments(&self) -> &[&'a str]

Get path segments as slice.

pub fn segment_count(&self) -> usize

Returns the number of segments in this path.

Trait Implementations

impl<'a, const MAX_DEPTH: usize> Debug for Path<'a, MAX_DEPTH>

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

Formats the value using the given formatter.

impl<'a, const MAX_DEPTH: usize> PartialEq for Path<'a, MAX_DEPTH>

fn eq(&self, other: &Path<'a, MAX_DEPTH>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
