Struct Component 

pub struct Component { /* private fields */ }

A validated component of a path.

Components are individual parts of a path, separated by dots. They cannot contain dots themselves. Empty components are allowed but will be filtered during path normalization.

Examples

// Valid components
let user = Component::new("user").unwrap();
let profile = Component::new("profile").unwrap();
let empty = Component::new("").unwrap();  // Empty is allowed

// Invalid components (only dots are forbidden)
assert!(Component::new("user.name").is_err()); // Contains dot

Implementations

impl Component

pub fn new(s: impl Into<String>) -> Result<Self, PathError>

Creates a new component from a string.

Errors

Returns an error only if the component contains a dot. Empty components are now allowed and will be filtered during path normalization.

pub fn as_str(&self) -> &str

Returns the component as a string slice.

Trait Implementations

impl AsRef<str> for Component

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Component

fn clone(&self) -> Component

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Component

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

Formats the value using the given formatter.

impl Display for Component

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

Formats the value using the given formatter.

impl FromStr for Component

type Err = PathError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Component

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Component

fn eq(&self, other: &Component) -> 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.

impl TryFrom<&str> for Component

type Error = PathError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for Component

type Error = PathError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Component
