Struct MultiVersionContainer 

pub struct MultiVersionContainer<T: Debug + Clone + Send + Sync + 'static> { /* private fields */ }

A thread-safe container for multi values.

This structure maintains multiple versions of a value, allowing for point-in-time queries and concurrent access patterns.

Implementations

impl<T: Debug + Clone + Send + Sync + 'static> MultiVersionContainer<T>

pub fn new() -> Self

Creates a new empty multi value container.

pub fn insert( &self, version: impl Into<CommitVersion>, value: T, ) -> Option<Option<T>>

Inserts a value at a specific version.

Returns the previous value at this version if one existed.

pub fn get(&self, version: impl Into<CommitVersion>) -> Option<T>

Gets the value that was active at a specific version.

This returns the value with the highest version that is <= the requested version.

pub fn get_or_tombstone( &self, version: impl Into<CommitVersion>, ) -> Option<Option<T>>

Gets the value that was active at a specific version.

This returns the value with the highest version that is <= the or the tombstone if it was explicitly removed

pub fn get_latest(&self) -> Option<T>

Gets the latest (most recent) value.

pub fn versions(&self) -> Vec<CommitVersion>

Gets all versions that have values.

pub fn remove(&self, version: impl Into<CommitVersion>) -> Option<Option<T>>

Removes a value at a specific version.

Returns the removed value if one existed.

pub fn len(&self) -> usize

Returns the number of versions stored.

pub fn is_empty(&self) -> bool

Checks if the container is empty.

pub fn clear(&self)

Clears all versions.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Debug + Clone + Send + Sync + 'static> Debug for MultiVersionContainer<T>

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

impl<T: Debug + Clone + Send + Sync + 'static> Default for MultiVersionContainer<T>

fn default() -> Self

Returns the “default value” for a type.
