Trait Implementations

impl AsRef<ExprValue> for ExprValue

fn as_ref(&self) -> &ExprValue

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ExprValue

fn clone(&self) -> ExprValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExprValue

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

Formats the value using the given formatter.

impl Display for ExprValue

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

Formats the value using the given formatter.

impl From<&String> for ExprValue

fn from(s: &String) -> Self

Converts to this type from the input type.

impl From<&str> for ExprValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<IndexMap<String, ExprValue>> for ExprValue

fn from(m: IndexMap<String, ExprValue>) -> Self

Converts to this type from the input type.

impl From<String> for ExprValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Vec<ExprValue>> for ExprValue

fn from(a: Vec<ExprValue>) -> Self

Converts to this type from the input type.

impl From<bool> for ExprValue

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for ExprValue

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i32> for ExprValue

fn from(n: i32) -> Self

Converts to this type from the input type.

impl PartialEq for ExprValue

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