Struct ArticleId 

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

Value Object: ArticleId

Represents a unique identifier for an article in the paywall system. Articles are identified by a slug or URL-safe identifier provided by the creator.

Domain Rules:

• Cannot be empty
• Must be between 1 and 256 characters
• Must be URL-safe (alphanumeric, hyphens, underscores only)
• Case-sensitive
• Immutable once created

This is a Value Object:

• Defined by its value, not identity
• Immutable
• Self-validating
• Compared by value equality

Implementations

impl ArticleId

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

Create a new ArticleId with validation

Errors

Returns error if:

• ID is empty
• ID is longer than 256 characters
• ID contains invalid characters (only a-z, A-Z, 0-9, -, _ allowed)

Examples

use allsource_core::domain::value_objects::ArticleId;

let article_id = ArticleId::new("my-awesome-article".to_string()).unwrap();
assert_eq!(article_id.as_str(), "my-awesome-article");

pub fn as_str(&self) -> &str

Get the string value

pub fn into_inner(self) -> String

Get the inner String (consumes self)

pub fn starts_with(&self, prefix: &str) -> bool

Check if this article ID starts with a specific prefix

pub fn ends_with(&self, suffix: &str) -> bool

Check if this article ID ends with a specific suffix

Trait Implementations

impl Clone for ArticleId

fn clone(&self) -> ArticleId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArticleId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ArticleId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ArticleId

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

Formats the value using the given formatter.

impl Hash for ArticleId

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 ArticleId

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for ArticleId

type Error = AllSourceError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self>

Performs the conversion.

impl TryFrom<String> for ArticleId

type Error = AllSourceError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self>

Performs the conversion.
