Trait Implementations

impl Clone for Region

fn clone(&self) -> Region

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Region

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

Formats the value using the given formatter.

impl Display for Region

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

Formats the value using the given formatter.

impl Drop for Region

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> FromValue<'a> for &'a Region

type Checker = GenericValueTypeOrNoneChecker<&'a Region>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl<'a> FromValue<'a> for Region

type Checker = GenericValueTypeOrNoneChecker<Region>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl PartialEq<Region> for Region

fn eq(&self, other: &Region) -> 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 StaticType for Region

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for Region

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ToValueOptional for Region

fn to_value_optional(s: Option<&Self>) -> Value

Convert an Option to a Value.

impl ValueType for Region

type Type = Region

Type to get the Type from.

impl Eq for Region

impl ValueTypeOptional for Region
