Struct MetadataIndex 

pub struct MetadataIndex {
    pub mode: CreationMode,
    pub entries: Vec<IndexEntry>,
    pub datasets: Vec<DatasetMetadata>,
}

The merged metadata index produced from one or more MetadataBlocks.

Fields

mode: CreationMode

Creation mode used.

entries: Vec<IndexEntry>

Ordered index entries (sorted by name for deterministic output).

datasets: Vec<DatasetMetadata>

Flattened list of all dataset metadata, in entry order.

Implementations

impl MetadataIndex

pub fn from_collective( datasets: Vec<DatasetMetadata>, ) -> Result<Self, FormatError>

Create a collective-mode index from a single block of datasets.

pub fn merge_blocks(blocks: &[MetadataBlock]) -> Result<Self, FormatError>

Merge multiple independently created metadata blocks into a single index.

Returns an error if any two blocks contain datasets with the same name.

pub fn find(&self, name: &str) -> Option<&DatasetMetadata>

Look up a dataset by name.

pub fn len(&self) -> usize

Number of datasets in the index.

pub fn is_empty(&self) -> bool

Whether the index is empty.
