Struct ShdfFile 

pub struct ShdfFile {
    pub datasets: Vec<Dataset>,
    pub global_attributes: Vec<(String, String)>,
}

An in-memory .shdf file.

Fields

datasets: Vec<Dataset>

Ordered list of datasets.

global_attributes: Vec<(String, String)>

File-level key/value string attributes.

Implementations

impl ShdfFile

pub fn new() -> Self

Create an empty ShdfFile.

pub fn add_dataset_f64(&mut self, name: &str, shape: Vec<usize>, data: Vec<f64>)

Append a Float64 dataset.

pub fn add_dataset_i32(&mut self, name: &str, shape: Vec<usize>, data: Vec<i32>)

Append an Int32 dataset.

pub fn add_global_attr(&mut self, key: &str, value: &str)

Add a global (file-level) key/value attribute.

pub fn get_f64(&self, name: &str) -> Option<&[f64]>

Look up a Float64 dataset by name and return its data slice.

pub fn get_i32(&self, name: &str) -> Option<&[i32]>

Look up an Int32 dataset by name and return its data slice.

pub fn to_bytes(&self) -> Vec<u8>

Serialize the file to a binary blob (little-endian).

pub fn from_bytes(data: &[u8]) -> Result<Self, String>

Deserialize a binary blob written by ShdfFile::to_bytes.

Returns Err(String) on any format violation.

pub fn write_to_text(&self) -> String

Return a human-readable summary of the file contents.
