Index metadata

Fields

uuid: Uuid

Unique ID across all dataset versions.

fields: Vec<i32>

Fields to build the index.

name: String

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

Performs copy-assignment from source.

impl Debug for Index

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

Formats the value using the given formatter.

impl DeepSizeOf for Index

fn deep_size_of_children(&self, context: &mut Context) -> usize

fn deep_size_of(&self) -> usize

Returns an estimation of a total size of memory owned by the object, including heap-managed storage.

impl From<&Index> for IndexMetadata

fn from(idx: &Index) -> Self

impl TryFrom<IndexMetadata> for Index

type Error = Error

The type returned in the event of a conversion error.

fn try_from(proto: IndexMetadata) -> Result<Self>

Performs the conversion.
