Struct Path 

pub struct Path { /* private fields */ }

(path feature) Accepts a filesystem path string.

Format checks (absolute/relative, extension) never touch the filesystem. The existence, kind, and permission checks do, and only when explicitly requested. readable/writable consult OS permission flags where available; where the OS exposes no such flag the check is a no-op that accepts.

Implementations

impl Path

pub fn with_meta(self, meta: Meta) -> Self

Attach human-facing metadata (name, description, examples, default, output conversion).

pub fn new() -> Self

pub fn absolute(self) -> Self

pub fn relative(self) -> Self

pub fn extension(self, extension: impl Into<String>) -> Self

Require the path to end in one of the allowed extensions (compared case-insensitively).

pub fn must_exist(self) -> Self

Require the path to exist on the filesystem.

pub fn kind(self, kind: PathKind) -> Self

Require the path to point at the given kind of entry (implies existence).

pub fn readable(self) -> Self

Require the path to be readable (implies existence).

pub fn writable(self) -> Self

Require the path to be writable (implies existence).

Trait Implementations

impl Clone for Path

fn clone(&self) -> Path

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Path

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

Formats the value using the given formatter.

impl Default for Path

fn default() -> Path

Returns the “default value” for a type.

impl Validator for Path

fn meta(&self) -> &Meta

This validator’s human-facing metadata.

fn meta_mut(&mut self) -> &mut Meta

Mutable access to this validator’s metadata (backs the WithMeta builder setters).

fn check(&self, value: &mut Value) -> Result<(), Error>

The validation rule: check (and coerce) value in place.

fn validate(&self, value: &mut Value) -> Result<(), Error>

Run check; on error attach this validator’s Meta (innermost wins); on success apply the output conversion in meta().convert, if any.
