Struct RelationVersionId 

pub struct RelationVersionId(pub String);

Opaque identifier for a relation version.

Each mutation to a relation produces a new version with a new RelationVersionId. The RelationId remains stable across versions.

Tuple Fields

0: String

Implementations

impl RelationVersionId

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

Creates an ID from a canonical family-qualified string or a validated payload that will be family-qualified.

Panics when the value is empty, non-canonical, or belongs to a different ID family. Use try_new for untrusted input.

pub fn try_new(value: impl Into<String>) -> Result<Self, IdParseError>

Fallible constructor for untrusted ID input or payloads.

pub fn generate() -> Self

Generate a new random UUID v4 ID.

pub fn as_str(&self) -> &str

Borrow as a string slice.

pub fn is_empty(&self) -> bool

Returns true if the inner string is empty.

Valid IDs are never empty; retained for source compatibility.
