Struct IdentifierScheme 

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

An extensible scheme name for an external identifier.

Schemes are deliberately strings rather than a closed enum. Core performs only bounded, transport-safe validation; standards-specific validation is a separate opt-in concern.

Implementations

impl IdentifierScheme

pub fn new(value: impl Into<String>) -> Result<Self>

Creates a scheme while preserving its exact spelling.

Errors

Returns ErrorKind::InvalidArgument when value is empty, exceeds MAX_IDENTIFIER_SCHEME_BYTES, or contains whitespace/control bytes.

pub fn as_str(&self) -> &str

Returns the exact scheme supplied by the caller.

pub fn into_string(self) -> String

Consumes the scheme and returns its owned string.

Trait Implementations

impl Clone for IdentifierScheme

fn clone(&self) -> IdentifierScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdentifierScheme

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

Formats the value using the given formatter.

impl Eq for IdentifierScheme

impl Hash for IdentifierScheme

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 Ord for IdentifierScheme

fn cmp(&self, other: &IdentifierScheme) -> 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 IdentifierScheme

fn eq(&self, other: &IdentifierScheme) -> 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 IdentifierScheme

fn partial_cmp(&self, other: &IdentifierScheme) -> 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.
