Struct Dataset 

pub struct Dataset {
    pub records: Vec<Record>,
}

A dataset is a homogeneous-ish collection of records. We don’t enforce schema — encodings pick which fields to use.

Fields

records: Vec<Record>

Implementations

impl Dataset

pub fn new(records: Vec<Record>) -> Self

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn fields(&self) -> Vec<String>

Names of fields seen across all records.

pub fn column_f64(&self, field: &str) -> Result<Vec<f64>>

pub fn column_str(&self, field: &str) -> Result<Vec<String>>

pub fn from_csv_path(path: impl AsRef<Path>) -> Result<Self>

Read a dataset from a CSV file. Numeric columns are auto-detected per cell — strings that parse as f64 become numbers.

pub fn from_json_str(s: &str) -> Result<Self>

Trait Implementations

impl Clone for Dataset

fn clone(&self) -> Dataset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dataset

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

Formats the value using the given formatter.

impl Default for Dataset

fn default() -> Dataset

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Dataset

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Dataset

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
