Struct PredefinedSplit

#[non_exhaustive]
pub struct PredefinedSplit {
    pub key: String,
    /* private fields */
}

Assigns input data to training, validation, and test sets based on the value of a provided key.

Supported only for tabular Datasets.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: String

Required. The key is a name of one of the Dataset’s data columns. The value of the key (either the label’s value or value in the column) must be one of {training, validation, test}, and it defines to which set the given piece of data is assigned. If for a piece of data the key is not present or has an invalid value, that piece is ignored by the pipeline.

Implementations

impl PredefinedSplit

pub fn new() -> Self

pub fn set_key<T: Into<String>>(self, v: T) -> Self

Sets the value of key.

Trait Implementations

impl Clone for PredefinedSplit

fn clone(&self) -> PredefinedSplit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PredefinedSplit

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

Formats the value using the given formatter.

impl Default for PredefinedSplit

fn default() -> PredefinedSplit

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PredefinedSplit

where PredefinedSplit: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for PredefinedSplit

fn typename() -> &'static str

The typename of this message.

impl PartialEq for PredefinedSplit

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

impl Serialize for PredefinedSplit

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
