Trait Implementations

impl Clone for FactValue

fn clone(&self) -> FactValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FactValue

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

Formats the value using the given formatter.

impl Display for FactValue

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

Formats the value using the given formatter.

impl From<&str> for FactValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for FactValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Vec<FactValue>> for FactValue

fn from(arr: Vec<FactValue>) -> Self

Converts to this type from the input type.

impl From<bool> for FactValue

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for FactValue

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i32> for FactValue

fn from(i: i32) -> Self

Converts to this type from the input type.

impl From<i64> for FactValue

fn from(i: i64) -> Self

impl PartialEq for FactValue

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