Enum ColumnData 

pub enum ColumnData {
    Strings(Vec<String>),
    Numeric(Vec<f64>),
    Categorical {
        codes: Vec<i32>,
        categories: Vec<String>,
    },
}

A metadata column with typed data.

Supports string, numeric, and categorical columns as found in .h5ad files.

Variants

Strings(Vec<String>)

Free-text string values.

Numeric(Vec<f64>)

Numeric (f64) values.

Categorical

Categorical data stored as integer codes indexing into a category list.

Fields

codes: Vec<i32>

categories: Vec<String>

Implementations

impl ColumnData

pub fn len(&self) -> usize

Number of elements in this column.

pub fn is_empty(&self) -> bool

Whether the column is empty.

pub fn as_strings(&self) -> Option<&Vec<String>>

Try to get as string slice. Returns None if not Strings variant.

pub fn as_numeric(&self) -> Option<&Vec<f64>>

Try to get as numeric slice. Returns None if not Numeric variant.

Trait Implementations

impl Clone for ColumnData

fn clone(&self) -> ColumnData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColumnData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ColumnData

fn eq(&self, other: &ColumnData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
