Struct Snapshot 

pub struct Snapshot { /* private fields */ }

An immutable snapshot of xDS resources for a node.

Snapshots are the primary unit of cache storage. Each snapshot contains resources organized by type, with per-type versioning.

impl Snapshot

pub fn builder() -> SnapshotBuilder

Create a new snapshot builder.

pub fn version(&self) -> &str

Get the global version of this snapshot.

pub fn created_at(&self) -> Instant

Get the creation timestamp.

pub fn get_resources(&self, type_url: TypeUrl) -> Option<&SnapshotResources>

Get resources for a specific type.

pub fn get_version(&self, type_url: TypeUrl) -> Option<&str>

Get the version for a specific resource type.

pub fn contains_type(&self, type_url: TypeUrl) -> bool
