Trait Implementations

impl Clone for Matrix

fn clone(&self) -> Matrix

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Matrix

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

Formats the value using the given formatter.

impl Default for Matrix

fn default() -> Self

Returns the “default value” for a type.

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

type Checker = GenericValueTypeOrNoneChecker<&'a Matrix>

Value type checker.

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

Get the contained value from a Value.

impl<'a> FromValue<'a> for Matrix

type Checker = GenericValueTypeOrNoneChecker<Matrix>

Value type checker.

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

Get the contained value from a Value.

impl PartialEq<Matrix> for Matrix

fn eq(&self, other: &Matrix) -> 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 Matrix

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for Matrix

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 Matrix

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

Convert an Option to a Value.

impl ValueType for Matrix

type Type = Matrix

Type to get the Type from.

impl Copy for Matrix

impl StructuralPartialEq for Matrix

impl ValueTypeOptional for Matrix
