Trait Implementations

impl<'arena> Clone for Variable<'arena>

fn clone(&self) -> Variable<'arena>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'arena> Debug for Variable<'arena>

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

Formats the value using the given formatter.

impl<'arena> Display for Variable<'arena>

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

Formats the value using the given formatter.

impl<'arena> PartialEq for Variable<'arena>

fn eq(&self, other: &Variable<'arena>) -> bool

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

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.

impl TryFrom<&Variable<'_>> for NaiveDateTime

type Error = VMError

The type returned in the event of a conversion error.

fn try_from(value: &Variable<'_>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&Variable<'_>> for Value

type Error = VMError

The type returned in the event of a conversion error.

fn try_from(value: &Variable<'_>) -> Result<Self, Self::Error>

Performs the conversion.
