Struct NoExternalBases 

pub struct NoExternalBases;

A DeltaBaseSource with no external bases: a pack must be self-contained (every delta’s base an earlier entry). Used for closure-profile packs, pack rewrites and tests.

Trait Implementations

impl Clone for NoExternalBases

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NoExternalBases

impl Debug for NoExternalBases

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

Formats the value using the given formatter.

impl Default for NoExternalBases

fn default() -> Self

Returns the “default value” for a type.

impl DeltaBaseSource for NoExternalBases

fn base(&mut self, _id: &Hash) -> Result<Option<Vec<u8>>, PackError>

Canonical object bytes for id, or None when this source may not provide it. “Not permitted” and “does not exist” MUST both be None: the decoder reports them identically, by design.

const VERIFIED: bool = false

Whether Self::base returns bytes already verified to be the object named by the requested id (the store’s read verifies).

fn base_with_admission( &mut self, id: &Hash, admit: impl FnOnce(usize) -> Result<(), PackError>, ) -> Result<Option<Vec<u8>>, PackError>

Fetch with allocation admission. The default charges after base returns; sources that know the length first should override this to call admit before allocating, as &ObjectStore does. Before returning Some(bytes), every override must successfully invoke admit exactly once with bytes.len() and propagate its error.

impl Eq for NoExternalBases

impl PartialEq for NoExternalBases

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
