Struct Delivery 

pub struct Delivery {
    pub cache: CachePolicy,
    pub cache_path: Option<PathBuf>,
    pub accept_partial: bool,
    pub watch: Option<WatchDelivery>,
    pub workers: Workers,
    pub batch_size: usize,
    pub order: ScanOrder,
}

How a request is carried out, which never changes what its answer says.

No Default, deliberately. Every field here is a decision its caller has already made, and the cache policy is the one that decides whether an answer touches the filesystem and whether it leaves a trace; a default one reads cache: Auto whatever the caller asked for, which is exactly how the watch session came to validate against a cache policy nobody had chosen and WatchCacheOnly became unreachable inside the engine (fdu-i18y). A caller that wants the ordinary delivery names it.

Fields

cache: CachePolicy

How the snapshot cache may be used.

cache_path: Option<PathBuf>

Where the snapshot for this root lives, or None for no cache at all.

accept_partial: bool

Whether a partial answer is accepted as a success.

watch: Option<WatchDelivery>

Whether the answer repeats as a watch, and how.

workers: Workers

Directory and content reader workers.

batch_size: usize

Maximum operations in one scanner batch.

order: ScanOrder

Directory traversal scheduling.

Implementations

impl Delivery

pub fn new(cache: CachePolicy, cache_path: Option<PathBuf>) -> Self

Ordinary execution settings with an explicitly chosen cache policy and location.

pub fn enumerate() -> impl Iterator<Item = Self>

Representative deliveries for checking policy independently of route. Worker counts and cache location are fixed; every cache, partial-answer, and watch choice is represented.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Delivery

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

Formats the value using the given formatter.

impl Eq for Delivery
