Enum ColumnKind 

#[non_exhaustive]
pub enum ColumnKind {
    Integer,
    Float,
    Boolean,
    Text,
    Mixed,
    MissingOnly,
}

A simple, inferred kind for a column (RFC-035 §5).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Integer

All non-missing cells are integers.

Float

All non-missing cells are numeric (integers and/or floats).

Boolean

All non-missing cells are booleans.

Text

All non-missing cells are text.

Mixed

A mix of incompatible kinds (for example text and numbers).

MissingOnly

Every cell in the column is missing.

Trait Implementations

impl Clone for ColumnKind

fn clone(&self) -> ColumnKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColumnKind

impl Debug for ColumnKind

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

Formats the value using the given formatter.

impl Display for ColumnKind

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

Formats the value using the given formatter.

impl Eq for ColumnKind

impl PartialEq for ColumnKind

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