Struct Namespace 

pub struct Namespace(/* private fields */);

A validated, opaque namespace identifier.

Construct via Namespace::parse or Namespace::local. The absence of From<String> / From<&str> impls is intentional — callers must validate.

Implementations

impl Namespace

pub const LOCAL: &'static str = "local"

The name of the default local namespace.

pub fn parse(value: &str) -> Result<Namespace, NamespaceError>

Parse and validate a namespace string.

Returns Err(NamespaceError) if the string is empty, too long, contains invalid characters, has empty segments, or ends with :.

pub fn local() -> Namespace

Construct the default "local" namespace (always valid; no allocation).

pub fn as_str(&self) -> &str

Return the namespace as a string slice.

pub fn into_inner(self) -> String

Consume the Namespace and return the underlying owned string.

Trait Implementations

impl AsRef<str> for Namespace

fn as_ref(&self) -> &str

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

impl Clone for Namespace

fn clone(&self) -> Namespace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Namespace

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Namespace

fn deserialize<D>(d: D) -> Result<Namespace, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Namespace

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

Formats the value using the given formatter.

impl Eq for Namespace

impl Hash for Namespace

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

where __H: Hasher,

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 Ord for Namespace

fn cmp(&self, other: &Namespace) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Namespace

fn eq(&self, other: &Namespace) -> 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 PartialOrd for Namespace

fn partial_cmp(&self, other: &Namespace) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Namespace

fn serialize<S>( &self, s: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Namespace

impl TryFrom<&str> for Namespace

type Error = NamespaceError

The type returned in the event of a conversion error.

fn try_from( value: &str, ) -> Result<Namespace, <Namespace as TryFrom<&str>>::Error>

Performs the conversion.

impl TryFrom<String> for Namespace

type Error = NamespaceError

The type returned in the event of a conversion error.

fn try_from( value: String, ) -> Result<Namespace, <Namespace as TryFrom<String>>::Error>

Performs the conversion.
