Struct Fetch 

pub struct Fetch<C> {
    pub data: C,
    pub kind: FetchKind,
    pub epoch: u64,
}

Fetch result from a worker source.

Fields

data: C

The data chunk (ignored for non-Data kinds).

kind: FetchKind

Marker kind.

epoch: u64

Epoch for seek invalidation (0 if unused).

Implementations

impl<C> Fetch<C>

pub fn new(data: C, is_eof: bool, epoch: u64) -> Self

Create a fetch result from the legacy is_eof: bool shape.

is_eof = true maps to FetchKind::NaturalEof; false to FetchKind::Data. Prefer the explicit constructors below.

pub fn data(data: C, epoch: u64) -> Self

Explicit data chunk.

pub fn epoch(&self) -> u64

Get the epoch.

pub fn failure(data: C, epoch: u64) -> Self

Explicit failure marker (distinct from natural EOF).

pub fn into_inner(self) -> C

Consume and return the inner data.

pub fn is_eof(&self) -> bool

True iff this is a natural-EOF marker. Does not cover Failure — callers must use is_failure() or is_terminal() for the broader “end of stream for any reason” check.

pub fn is_terminal(&self) -> bool

True iff this is any terminal marker (natural EOF or failure).

Trait Implementations

impl<C: Clone> Clone for Fetch<C>

fn clone(&self) -> Fetch<C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: Debug> Debug for Fetch<C>

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

Formats the value using the given formatter.
