Struct HDF5Group 

pub struct HDF5Group { /* private fields */ }

An HDF5 group — a container for datasets and other groups.

Groups can be navigated by name (like a filesystem). Internally, HDF5 uses two completely different mechanisms depending on the object header version:

• v1 groups: Symbol table message → B-tree v1 (type 0) + local heap for names
• v2 groups: Inline link messages (small groups) or link info message → fractal heap + B-tree v2 (large groups)

Implementations

impl HDF5Group

pub fn new( name: String, header: ObjectHeader, reader: Arc<dyn AsyncFileReader>, raw_reader: Arc<dyn AsyncFileReader>, superblock: Arc<Superblock>, ) -> Self

Create a new group from its parsed object header.

pub fn name(&self) -> &str

The group’s name (not the full path).

pub fn header(&self) -> &ObjectHeader

Access the object header.

pub async fn children(&self) -> Result<Vec<ChildLink>>

List all child links in this group.

pub async fn group(&self, name: &str) -> Result<HDF5Group>

Get a child group by name.

pub async fn dataset(&self, name: &str) -> Result<HDF5Dataset>

Get a child dataset by name.

pub async fn child_header(&self, name: &str) -> Result<(u64, ObjectHeader)>

Get a child’s object header by name (returns the header without assuming whether it’s a group or dataset).

pub async fn navigate(&self, path: &str) -> Result<HDF5Group>

Navigate to a group by slash-separated path (e.g., “science/LSAR/GCOV”).

pub async fn group_names(&self) -> Result<Vec<String>>

List all child group names.

pub async fn dataset_names(&self) -> Result<Vec<String>>

List all child dataset names.

pub fn reader(&self) -> &Arc<dyn AsyncFileReader>

Access the reader.

pub fn superblock(&self) -> &Arc<Superblock>

Access the superblock.

pub async fn attributes(&self) -> Vec<Attribute>

Get all attributes attached to this group, resolving vlen data.

pub async fn attribute(&self, name: &str) -> Option<Attribute>

Get a single attribute by name.
