Struct SnapshotReadRequest 

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

Original mutation identity and independently declared exact snapshot-list payload.

This request does not inspect journals or reserve calls. The caller supplies the observation digest from its own exact retained intent/reservation owner; digest equality alone proves neither retention nor spending admission. Challenge freshness, authenticated context and prior per-call accounting stay integration-owned. Only list is implemented; metadata/data codecs remain pending.

Implementations

impl<'a> SnapshotReadRequest<'a>

pub fn new( plan: &OperationPlanRecord, sequence: u64, wire: &'a IcManagementRequestRecord, observation: &ArtifactChecksumRecord, challenge: ArtifactChecksumRecord, max_remote_observations: u32, ) -> Result<Self, SnapshotReadRequestError>

Bind exact list bytes to the original operation target and separate observation digest.

Errors

Rejects unsupported methods, unknown operations, changed target/payload and excess ceiling.

pub const fn binding(&self) -> &OperationBindingRecord

Read exact original mutation intent/context/target/request identity.

pub const fn wire(&self) -> &IcManagementRequestRecord

Read validated exact snapshot-list routing/method/Candid bytes.

pub const fn challenge(&self) -> &ArtifactChecksumRecord

Read caller-owned challenge; its value does not establish freshness.

pub const fn max_remote_observations(&self) -> u32

Read descriptive invocation ceiling, distinct from spending allowances.

pub fn digest(&self) -> ArtifactChecksumRecord

Hash full original intent/sequence, separate exact read payload, challenge and ceiling.

Encoding: NUL-terminated ASCII v1 domain, 64 ASCII intent bytes, u64 big-endian sequence, 64 ASCII list wire-digest bytes, 64 ASCII challenge bytes and u32 big-endian ceiling. Observed visibility/evidence are excluded.
