Implementations

impl Dataset

pub fn from_f64_slice(name: &str, data: &[f64], shape: DatasetShape) -> Self

Constructs a dataset from a slice of f64 values.

pub fn from_f32_slice(name: &str, data: &[f32], shape: DatasetShape) -> Self

Constructs a dataset from a slice of f32 values.

pub fn from_i32_slice(name: &str, data: &[i32], shape: DatasetShape) -> Self

Constructs a dataset from a slice of i32 values.

pub fn to_f64_vec(&self) -> Result<Vec<f64>, String>

Decodes the raw bytes back into a Vecf64`.

pub fn to_f32_vec(&self) -> Result<Vec<f32>, String>

pub fn to_i32_vec(&self) -> Result<Vec<i32>, String>

Decodes the raw bytes back into a Veci32`.

pub fn add_attribute(&mut self, attr: Attribute)

Appends an attribute to this dataset.

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

Looks up an attribute by name.
