Struct IdempotencyToken 

pub struct IdempotencyToken(pub String);

Deduplication token attached to an Event.

Produced by the configured IdempotencyStrategy and, when an IdempotencyStorageProvider is wired, used to reserve uniqueness before the event is written. Accepts arbitrary strings — interpretation is left entirely to the caller.

Implementations

impl IdempotencyToken

pub fn new(token: String) -> Self

Wraps a string as a token.

pub fn as_str(&self) -> &str

Returns the token as a &str for comparison or logging.

pub fn as_bytes(&self) -> &[u8]

Returns the raw bytes of the token — convenient for hashing backends such as Redis keys or BLAKE3.

Trait Implementations

impl Clone for IdempotencyToken

fn clone(&self) -> IdempotencyToken

Returns a duplicate of the value.
