Struct VersionTag 

pub struct VersionTag { /* private fields */ }

A named version tag that captures a complete dataset state snapshot at a specific serial number. Tags are immutable once created and enable reproducible training and validation by referencing an exact dataset state.

Implementations

impl VersionTag

pub fn id(&self) -> u64

Returns the tag’s unique identifier.

pub fn dataset_id(&self) -> DatasetID

Returns the dataset ID this tag belongs to.

pub fn name(&self) -> &str

Returns the tag name.

pub fn serial(&self) -> u64

Returns the changelog serial number this tag references.

pub fn description(&self) -> &str

Returns the tag description.

pub fn created_by(&self) -> &str

Returns the username that created this tag.

pub fn created_at(&self) -> DateTime<Utc>

Returns when this tag was created.

pub fn image_count(&self) -> u64

Returns the number of images at tag time.

pub fn annotation_counts(&self) -> &HashMap<String, u64>

Returns annotation counts by type (e.g., {"box": 150000, "seg": 20000}).

pub fn sensor_counts(&self) -> &HashMap<String, u64>

Returns sensor data counts by type (e.g., {"lidar": 25000}).

pub fn label_count(&self) -> u64

Returns the number of labels at tag time.

pub fn annotation_set_count(&self) -> u64
