Struct DataFrame

pub struct DataFrame {
    pub constants: HashMap<Key, DataValue>,
    pub dataframe: ColumnFrame,
    pub metadata: HashMap<String, DataValue>,
}

DataFrame holds information about ColumnFrame. This is used to store the data and the metadata for the candidates.

Fields

constants: HashMap<Key, DataValue>

Constants for the dataframe - mikro optimization for the data Values which is constant for the whole dataframe are stored here

dataframe: ColumnFrame

Dataframe with the candidates

metadata: HashMap<String, DataValue>

Metadata for the dataframe. Here you can store the information about the dataframe

Trait Implementations

impl Clone for DataFrame

fn clone(&self) -> DataFrame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataFrame

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

Formats the value using the given formatter.

impl Default for DataFrame

fn default() -> DataFrame

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DataFrame

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DataFrame

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

Formats the value using the given formatter.

impl From<ColumnFrame> for DataFrame

fn from(dataframe: ColumnFrame) -> Self

Converts to this type from the input type.

impl From<HashMap<String, Vec<DataValue>>> for DataFrame

fn from(dataframe: HashMap<String, Vec<DataValue>>) -> Self

Converts to this type from the input type.

impl From<SizedHashMap<SmartString<LazyCompact>, Vec<DataValue>>> for DataFrame

fn from(dataframe: MLChefMap) -> Self

Converts to this type from the input type.

impl From<Vec<(Key, Vec<DataValue>)>> for DataFrame

Converts to this type from the input type.

impl From<Vec<HashMap<Key, DataValue>>> for DataFrame

fn from(dataframe: Vec<HashMap<Key, DataValue>>) -> Self

Converts to this type from the input type.

impl From<Vec<SizedHashMap<Key, DataValue>>> for DataFrame

fn from(dataframe: Vec<HashMap<Key, DataValue>>) -> Self

impl PartialEq for DataFrame

fn eq(&self, other: &DataFrame) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.
