Struct CachedPocketIcBaseline 

pub struct CachedPocketIcBaseline<T> { /* private fields */ }

One owned PocketIC instance/server record with snapshots and caller metadata.

The value contains no synchronization. A super::PocketIcBaselineRecipe can own it as its fixture in a super::CachedPocketIcBaselinePool.

Implementations

impl<T> CachedPocketIcBaseline<T>

pub fn capture<I>( instance: PocketIcInstance<PocketIc>, targets: I, metadata: T, ) -> Result<Self, ControllerSnapshotError>

where I: IntoIterator<Item = CanisterSnapshotTarget>,

Capture a cached baseline with an explicit sender for every canister.

Capture is ordered and transactional as documented by PocketIcSnapshotExt::capture_snapshots. No sender fallback is performed.

pub fn restore( &self, funding: SnapshotRestoreFunding, ) -> Result<(), ControllerSnapshotError>

Restore with exactly the captured senders and selected cycle funding.

pub const fn pocket_ic(&self) -> &PocketIc

Borrow the owned PocketIC instance behind this cached baseline.

pub fn snapshot_count(&self) -> usize

Return the number of canisters captured by this baseline.

pub fn snapshot_canister_ids(&self) -> impl Iterator<Item = Principal> + '_

Iterate over captured canister ids in deterministic principal order.

pub const fn metadata(&self) -> &T

Borrow the captured metadata associated with this cached baseline.

pub const fn metadata_mut(&mut self) -> &mut T

Mutably borrow the captured metadata associated with this cached baseline.
