Implementations

impl HistogramValue

pub fn to_bool(&self) -> bool

Converts any value to a boolean value.

pub fn to_i64(&self) -> i64

Converts any value to an integer number.

pub fn to_f32(&self) -> f32

Converts any value to a floating-point number.

pub fn to_opt_bool(&self) -> Option<bool>

Converts the value to a boolean value if the value is an boolean type, otherwise this method returns None.

pub fn to_opt_i64(&self) -> Option<i64>

Converts the value to an integer number if the value is an integer type or floating-point type, otherwise this method returns None.

pub fn to_opt_f32(&self) -> Option<f32>

Converts the value to a floating-point number if the value is an integer type or floating-point type, otherwise this method returns None.

pub fn to_opt_string(&self) -> Option<String>

Converts the value to a string if the value is a string type, otherwise this method returns None.

Trait Implementations

impl Clone for HistogramValue

fn clone(&self) -> HistogramValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistogramValue

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

Formats the value using the given formatter.

impl Display for HistogramValue

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

Formats the value using the given formatter.

impl PartialEq for HistogramValue

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.
