Struct ProjectionName 

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

Value Object: ProjectionName

Represents the name of a projection in the event store. Projections are materialized views derived from event streams.

Domain Rules:

• Cannot be empty
• Must be between 1 and 100 characters
• Must be alphanumeric with hyphens/underscores only
• Case-sensitive
• Immutable once created
• Must be unique within a tenant

This is a Value Object:

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

Implementations

impl ProjectionName

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

Create a new ProjectionName with validation

Errors

Returns error if:

• Name is empty
• Name is longer than 100 characters
• Name contains invalid characters

Examples

use allsource_core::domain::value_objects::ProjectionName;

let name = ProjectionName::new("user_snapshot".to_string()).unwrap();
assert_eq!(name.as_str(), "user_snapshot");

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 name starts with a prefix

Useful for grouping projections by naming convention.

Examples

use allsource_core::domain::value_objects::ProjectionName;

let name = ProjectionName::new("user_snapshot".to_string()).unwrap();
assert!(name.starts_with("user"));
assert!(!name.starts_with("order"));

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

Check if this name ends with a suffix

Useful for identifying projection types by naming convention.

Examples

use allsource_core::domain::value_objects::ProjectionName;

let name = ProjectionName::new("user_snapshot".to_string()).unwrap();
assert!(name.ends_with("snapshot"));
assert!(!name.ends_with("counter"));

pub fn contains(&self, pattern: &str) -> bool

Check if this name contains a substring

Trait Implementations

impl AsRef<str> for ProjectionName

fn as_ref(&self) -> &str

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

impl Clone for ProjectionName

fn clone(&self) -> ProjectionName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectionName

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProjectionName

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProjectionName

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

Formats the value using the given formatter.

impl Hash for ProjectionName

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 ProjectionName

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

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 ProjectionName

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 ProjectionName

type Error = AllSourceError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl Eq for ProjectionName

impl StructuralPartialEq for ProjectionName
