Struct BackendOptions 

pub struct BackendOptions {
    pub dependency_tracking: bool,
    pub active_tracking: bool,

    pub num_workers: Option<usize>,
    pub small_preallocation: bool,

}

Fields

dependency_tracking: bool

Enables dependency tracking.

When disabled: No state changes are allowed. Tasks will never reexecute and stay cached forever.

active_tracking: bool

Enables active tracking.

Automatically disabled when dependency_tracking is disabled.

When disabled: All tasks are considered as active.

storage_mode: Option<StorageMode>

Enables the backing storage.

num_workers: Option<usize>

Number of tokio worker threads. It will be used to compute the shard amount of parallel datastructures. If None, it will use the available parallelism.

small_preallocation: bool

Avoid big preallocations for faster startup. Should only be used for testing purposes.

eviction_mode: EvictionMode

Strategy for evicting evictable tasks from in-memory storage after a snapshot. This reclaims memory by clearing persisted data that can be re-loaded from disk on demand. This is an EXPERIMENTAL FEATURE under development

Trait Implementations

impl Default for BackendOptions

fn default() -> Self
