Enum DbValue 

pub enum DbValue {
    Int(i64),
    Float(f64),
    Text(String),
    Bool(bool),
    Null,
}

A column value in the simulation database.

Variants

Int(i64)

Integer value.

Float(f64)

Floating-point value.

Text(String)

Text value.

Bool(bool)

Boolean value.

Null

Null / missing value.

Implementations

impl DbValue

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

Return Some(f64) if this value is Float or Int, else None.

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

Return Some(&str) if this value is Text, else None.

Trait Implementations

impl Clone for DbValue

fn clone(&self) -> DbValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DbValue

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

Formats the value using the given formatter.

impl From<&str> for DbValue

fn from(v: &str) -> Self

Converts to this type from the input type.

impl From<bool> for DbValue

fn from(v: bool) -> Self

Converts to this type from the input type.

impl From<f64> for DbValue

fn from(v: f64) -> Self

Converts to this type from the input type.

impl From<i64> for DbValue

fn from(v: i64) -> Self

Converts to this type from the input type.

impl PartialEq for DbValue

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