Struct IcObservationRequest 

pub struct IcObservationRequest<'a> { /* private fields */ }

Structural binding to an original pending mutation and its reserved IC observation.

Retain original observation bytes before reserving their existing payload digest. This request neither spends nor proves dispatch custody, fresh read permission, authentication or effect attribution. Recovery never permits repeating a lost call.

Implementations

impl<'a> IcObservationRequest<'a>

pub fn new( plan: &'a OperationPlanRecord, operation_sequence: u64, journal: &AttemptJournalRecord, mutation: &'a IcManagementRequestRecord, payload: &'a IcManagementRequestRecord, ) -> Result<Self, IcObservationRequestError>

Bind original mutation bytes and exact already reserved status/list bytes.

Both payloads must name the same original target. Observation identity reuses the existing IC payload digest; no second hash or journal owner is introduced.

Errors

Rejects changed authority/payloads or missing original pending reservations.

pub const fn plan(&self) -> &OperationPlanRecord

Read the full original context, inventory and selection.

pub const fn mutation(&self) -> &'a IcManagementRequestRecord

Read the exact original mutation, never an executable retry.

pub const fn payload(&self) -> &'a IcManagementRequestRecord

Read exact observation receiver, routing target, method and Candid bytes.

pub const fn authority(&self) -> &AttemptAuthorityRecord

Read the original operation authority and immutable attempt limits.

pub const fn mutation_attempt(&self) -> u32

Read the original unresolved mutation attempt.

pub const fn observation_attempt(&self) -> u32

Read the original already consumed observation attempt.

pub fn validate_journal( &self, journal: &AttemptJournalRecord, ) -> Result<(), IcObservationRequestError>

Recheck current exact reservations and original observation bytes without IO.

Errors

Rejects changed authority, settled/replaced attempts or different reserved bytes.
