Struct ExternalIdentifier 

pub struct ExternalIdentifier { /* private fields */ }

An identifier assigned by an external standard, vendor, or application.

This value does not replace a PostProject object ID. It is opaque to core unless a caller explicitly applies a scheme-specific validator.

Implementations

impl ExternalIdentifier

pub fn new( scheme: IdentifierScheme, value: impl Into<String>, qualifier: Option<String>, ) -> Result<Self>

Creates an external identifier without normalizing its value.

Errors

Returns ErrorKind::InvalidArgument when the value or qualifier is empty when present, or exceeds its documented byte limit.

pub const fn scheme(&self) -> &IdentifierScheme

Returns the identifier scheme.

pub fn value(&self) -> &str

Returns the exact, opaque identifier value.

pub fn qualifier(&self) -> Option<&str>

Returns the optional exact scope or qualifier.

Trait Implementations

impl Clone for ExternalIdentifier

fn clone(&self) -> ExternalIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternalIdentifier

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

Formats the value using the given formatter.

impl Eq for ExternalIdentifier

impl Hash for ExternalIdentifier

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 ExternalIdentifier

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