Struct EventId 

pub struct EventId {
    pub scheme: EventIdScheme,
    pub value: String,
}

External identifier for an event, scoped by its issuing scheme.

Two EventId values are equal iff both their EventIdScheme and their value are equal. Equality is structural — no per-scheme canonicalisation is performed.

Example

use event_matcher::{EventId, EventIdScheme};

let a = EventId::new(EventIdScheme::Eventbrite, "123456789").unwrap();
let b = EventId::new(EventIdScheme::Eventbrite, " 123456789 ").unwrap();
assert_eq!(a, b, "values are trimmed at construction");
assert!(EventId::new(EventIdScheme::Eventbrite, "").is_none());

Fields

scheme: EventIdScheme

The issuing scheme.

value: String

The identifier value, trimmed of surrounding whitespace.

Implementations

impl EventId

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

Construct an EventId, trimming the value of surrounding whitespace. Returns None if the trimmed value is empty.

No further normalisation is applied — different schemes have different rules and the crate makes no assumptions.

Example

use event_matcher::{EventId, EventIdScheme};

let id = EventId::new(EventIdScheme::Wikidata, "  Q15290  ").unwrap();
assert_eq!(id.value, "Q15290");

assert!(EventId::new(EventIdScheme::Wikidata, "   ").is_none());

Trait Implementations

impl Clone for EventId

fn clone(&self) -> EventId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EventId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EventId

impl Hash for EventId

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 EventId

fn eq(&self, other: &EventId) -> 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 Serialize for EventId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
