Struct ExecutionContextBuilder 

pub struct ExecutionContextBuilder { /* private fields */ }

Declarative construction of an ExecutionContext.

Implementations

impl ExecutionContextBuilder

pub const fn memory_budget(self, budget: MemoryBudget) -> Self

Replaces the automatic execution budget (a share of physical memory, or MOLFRAME_MEMORY_BUDGET; see MemoryBudget::auto).

pub fn cancellation(self, token: CancellationToken) -> Self

Uses an existing cancellation domain.

pub const fn scratch_policy(self, policy: ScratchPolicy) -> Self

Replaces the reusable scratch policy.

pub fn temp_storage_policy(self, policy: TempStoragePolicy) -> Self

Replaces the temporary-storage policy.

pub const fn worker_budget(self, workers: usize) -> Self

Caps native tasks submitted by one operation to the shared worker pool.

pub const fn image_search_limit(self, images: usize) -> Self

Replaces the default ceiling on candidate symmetry images a crystal search may examine.

pub fn build(self) -> Result<ExecutionContext, ContextError>

Validates policy relationships and constructs the context.

Errors

Returns ContextError if reusable scratch could exceed the complete execution-memory budget or spill is configured with no disk capacity.
