Implementations

impl Value

pub fn as_f64(&self) -> Option<f64>

Try to extract as f64, coercing integers and datetimes.

pub fn as_str(&self) -> Option<&str>

Try to extract as string representation.

pub fn is_na(&self) -> bool

Check if this is NA/missing.

pub fn is_datetime(&self) -> bool

Check if this is a DateTime value.

pub fn from_timestamp(secs: i64) -> Self

Create a DateTime from seconds since Unix epoch.

pub fn to_group_key(&self) -> String

Convert to a string for display/grouping purposes.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

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