SubscriberCheckpoint

evm_fork_cache::reactive

Struct SubscriberCheckpoint 

Source 
pub struct SubscriberCheckpoint(/* private fields */);
Expand description

Opaque source checkpoint associated with a delivered batch.

Unlike SubscriberDeliveryToken, which identifies the delivery to acknowledge, this value describes provider-specific resume state. The core crate persists and returns the bytes without interpreting their format.

Implementations§

Source§

impl SubscriberCheckpoint

Source

pub fn new(bytes: Vec<u8>) -> Self

Source

pub fn as_bytes(&self) -> &[u8] ⓘ

Borrow the opaque checkpoint bytes.

Source

pub fn into_bytes(self) -> Vec<u8> ⓘ
