Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

impl Debug for Value

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

Formats the value using the given formatter. Read more

impl PartialEq<Value> for Value

fn eq(&self, other: &Value) -> bool

This method tests for self and other values to be equal, and is used by ==. Read more

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
