Struct H5Group 

pub struct H5Group { /* private fields */ }

A handle to an HDF5 group.

Groups are containers for datasets and other groups. The root group is always available via H5File::root_group.

Implementations

impl H5Group

pub fn name(&self) -> &str

Return the name (path) of this group.

pub fn new_dataset<T: H5Type>(&self) -> DatasetBuilder<T>

Start building a new dataset in this group.

The dataset will be registered as a child of this group in the HDF5 file hierarchy.

pub fn create_group(&self, name: &str) -> Result<H5Group>

Create a sub-group within this group.

Creates a real HDF5 group with its own object header.

pub fn group(&self, name: &str) -> Result<H5Group>

Open an existing sub-group by name (read mode).

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

List dataset names that are direct children of this group.

pub fn write_vlen_strings(&self, name: &str, strings: &[&str]) -> Result<()>

Create a variable-length string dataset and write data within this group.

pub fn write_vlen_strings_compressed( &self, name: &str, strings: &[&str], chunk_size: usize, pipeline: FilterPipeline, ) -> Result<()>

Create a chunked, compressed variable-length string dataset within this group.

pub fn create_appendable_vlen_dataset( &self, name: &str, chunk_size: usize, pipeline: Option<FilterPipeline>, ) -> Result<()>

Create an empty chunked vlen string dataset ready for incremental appends.

pub fn append_vlen_strings(&self, name: &str, strings: &[&str]) -> Result<()>

Append variable-length strings to an existing chunked vlen string dataset.

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

List sub-group names that are direct children of this group.
