Struct SuperVersionHandle 

pub struct SuperVersionHandle { /* private fields */ }

RAII handle for SuperVersion access

This provides a convenient way to access a SuperVersion with automatic cleanup. The handle can be cloned to share access across threads.

Implementations

impl SuperVersionHandle

pub fn new(version_set: Arc<VersionSet>) -> Self

Create a new handle from a VersionSet

pub fn with_snapshot(version_set: Arc<VersionSet>, seqno: u64) -> Self

Create a handle with a registered snapshot

pub fn version(&self) -> &SuperVersion

Get the SuperVersion

pub fn snapshot_seqno(&self) -> Option<u64>

Get the snapshot sequence number (if any)

Trait Implementations

impl Clone for SuperVersionHandle

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for SuperVersionHandle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
