Enum Checkpoint 

#[non_exhaustive]
pub enum Checkpoint {
    Sequential(SequentialCheckpoint),
    Indexed(IndexedCheckpoint),
}

One apply-time checkpoint, emitted at a natural recovery boundary.

Two variants, one per apply driver. The schema_version field on each inner struct lets a future resume reader refuse to consume a checkpoint from an incompatible build rather than silently misinterpret its fields.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Sequential(SequentialCheckpoint)

Sequential apply driver checkpoint. Emitted per top-level chunk and per DEFLATE block inside a long SqpkFile::AddFile.

Indexed(IndexedCheckpoint)

Indexed apply driver checkpoint. Emitted per target and every 64 regions inside a long target.

Trait Implementations

impl Clone for Checkpoint

fn clone(&self) -> Checkpoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Checkpoint

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

Formats the value using the given formatter.

impl PartialEq for Checkpoint

fn eq(&self, other: &Checkpoint) -> 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 Eq for Checkpoint
