Trait Implementations

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

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.

impl<'arena> Serialize for Variable<'arena>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

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.
