Struct PartitionSpec 

pub struct PartitionSpec { /* private fields */ }

Phase-1 partition specification for a context namespace.

This intentionally models only identity partition fields. More advanced Lance partition transforms (bucket, truncate, time transforms) can be layered in once the namespace resolver grows past the single-partition path.

Implementations

impl PartitionSpec

pub fn new<I, S>(fields: I) -> Result<PartitionSpec, Error>

where I: IntoIterator<Item = S>, S: Into<String>,

Create a v1 identity partition spec from ordered field names.

pub fn with_version<I, S>( version: i32, fields: I, ) -> Result<PartitionSpec, Error>

where I: IntoIterator<Item = S>, S: Into<String>,

Create an identity partition spec with an explicit version.

pub fn tenant() -> PartitionSpec

pub fn tenant_source() -> PartitionSpec

pub fn version(&self) -> i32

pub fn fields(&self) -> &[String]

Trait Implementations

impl Clone for PartitionSpec

fn clone(&self) -> PartitionSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionSpec

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

Formats the value using the given formatter.

impl Eq for PartitionSpec

impl PartialEq for PartitionSpec

fn eq(&self, other: &PartitionSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
