Struct FakeHost 

pub struct FakeHost { /* private fields */ }

Deterministic fake host boundary for resource status simulations.

Implementations

impl FakeHost

pub const fn new() -> Self

Creates a fake host with status revisions starting at one.

pub fn apply_result<C: Clone, O>( &mut self, ledger: &mut ResourceLedger<C>, result: &TransactionResult<C, O>, ) -> Vec<FakeHostEvent>

Applies a transaction result to the ledger and returns explicit statuses.

pub fn observe<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, ) -> FakeHostEvent

Produces a custom successful-open status event.

pub fn observe_outcome<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, status: HostResourceOutcome, ) -> FakeHostEvent

Produces a custom host outcome and classifies it through the ledger.

pub fn open_succeeded<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, ) -> FakeHostEvent

Reports that an open command succeeded.

pub fn open_succeeds_later<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, ) -> FakeHostEvent

Reports that an earlier open command succeeded after later graph work.

pub fn open_failed<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, reason: impl Into<String>, ) -> FakeHostEvent

Reports that an open command failed.

pub fn close_succeeded<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, ) -> FakeHostEvent

Reports that a close command succeeded.

pub fn close_failed<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, reason: impl Into<String>, ) -> FakeHostEvent

Reports that a close command failed at the host boundary.

pub fn resource_lost<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, resource_key: ResourceKey, scope: ScopeId, command_revision: Revision, reason: impl Into<String>, ) -> FakeHostEvent

Reports that a resource was externally lost outside graph propagation.

pub fn duplicate_status<C: Clone>( &mut self, ledger: &mut ResourceLedger<C>, event: &FakeHostEvent, ) -> FakeHostEvent

Re-delivers a previous host status without assigning a new host revision.

Trait Implementations

impl Clone for FakeHost

fn clone(&self) -> FakeHost

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FakeHost

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FakeHost

fn default() -> Self

Returns the “default value” for a type.

impl Eq for FakeHost

impl PartialEq for FakeHost

fn eq(&self, other: &FakeHost) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
