Enum Predicate 

pub enum Predicate {
    Eq {
        column: String,
        value: Value,
    },
    NotNull {
        column: String,
    },
    ModEqInt64 {
        column: String,
        modulus: i64,
        equals: i64,
    },
}

A predicate used by DataFrame::filter.

Variants

Eq

Keep rows where column == value.

Fields

column: String

value: Value

NotNull

Keep rows where column is not null.

Fields

column: String

ModEqInt64

Keep rows where column % modulus == equals (Int64 only).

Fields

column: String

modulus: i64

equals: i64

Trait Implementations

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

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

Formats the value using the given formatter.

impl PartialEq for Predicate

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