Trait QueryPreparedEnvelope 

pub trait QueryPreparedEnvelope: ConnectionExt + Sized {
    // Provided methods
    fn prepared_envelopes(
        &self,
        intent_id: ID,
    ) -> Result<Option<Vec<u8>>, StorageError> { ... }
    fn compare_and_set_prepared_envelopes(
        &self,
        intent_id: ID,
        expected: Option<&[u8]>,
        replacement: Option<&[u8]>,
    ) -> Result<bool, StorageError> { ... }
}

Exact attempt bytes kept across retries of one logical intent.

Provided Methods

fn prepared_envelopes( &self, intent_id: ID, ) -> Result<Option<Vec<u8>>, StorageError>

Read the persisted attempt. None means no attempt is currently prepared.

fn compare_and_set_prepared_envelopes( &self, intent_id: ID, expected: Option<&[u8]>, replacement: Option<&[u8]>, ) -> Result<bool, StorageError>

Replace only the exact attempt the caller read under the state writer. Late publish replies must use this check before attaching receipt metadata.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
