Expand description

Lance-specific operations exposed beyond the format-agnostic Dataset trait.

Required Methods§

Source

fn list_versions<'life0, 'life1, 'async_trait>( &'life0 self, branch: Option<&'life1 str>, tagged_only: bool, ) -> Pin<Box<dyn Future<Output = Result<Vec<VersionInfo>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

List versions on branch (defaults to main when None). When tagged_only is true, drops untagged versions from the result.

Source

fn list_branches<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<BranchInfo>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

List every branch the dataset has, including the default main.

Source

fn list_indices<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<IndexInfo>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

List indices defined on the active version of the dataset.

Source

fn list_tags<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<TagInfo>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

List every tag in the dataset, regardless of branch.
