Struct SnapshotAnchor 

pub struct SnapshotAnchor {
    pub high_watermark: u64,
    pub blob_ref: String,
    pub content_hash: String,
}

A pointer from a cache snapshot blob to a durable event-store high-watermark.

blob_ref and content_hash are intentionally opaque strings. The cache owns the storage backend and hash algorithm; the event store only persists the metadata needed to find the blob and prove the fetched bytes match the snapshot that was anchored.

Fields

high_watermark: u64

Largest event-store seq covered by the snapshot.

blob_ref: String

Cache-owned reference to the snapshot blob.

content_hash: String

Cache-owned content hash for the snapshot blob.

Implementations

impl SnapshotAnchor

pub fn new( high_watermark: u64, blob_ref: impl Into<String>, content_hash: impl Into<String>, ) -> Self

Creates a new SnapshotAnchor.

Trait Implementations

impl Clone for SnapshotAnchor

fn clone(&self) -> SnapshotAnchor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotAnchor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SnapshotAnchor

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SnapshotAnchor

impl PartialEq for SnapshotAnchor

fn eq(&self, other: &SnapshotAnchor) -> 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 SnapshotAnchor

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
