Enum Provenance 

pub enum Provenance {
    UserProvided,
    HostProvided,
}

A blob’s Local story: where its bytes live while the blob is Local, and whether bringing it back from Remote needs a destination path. Orthogonal to CacheFill (the Remote story) — a blob declares both.

The cache never enters into this: a Local blob is not a cache copy. Provenance decides which of the two Local homes holds it, and what make_local does to restore it.

Variants

UserProvided

The user’s own file at a path; coven references it but does not own it (tracked as an external ref — see local_blob_refs). make_local writes the bytes back to a user file, so it needs a destination path.

HostProvided

The host hands coven the data; coven keeps its own copy in the local store (storage/local/<namespace>/<id>, see [local_files]). make_local restores it to the local store, so it needs no path.

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Provenance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Provenance

fn deserialize<__D>( __deserializer: __D, ) -> Result<Provenance, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Provenance

fn eq(&self, other: &Provenance) -> 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.

impl Serialize for Provenance

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Provenance

impl Eq for Provenance

impl StructuralPartialEq for Provenance
