Struct Context

pub struct Context(/* private fields */);

Implementations

impl Context

pub fn new(display: Option<&Display>) -> Result<Context, Error>

Creates a new Context which acts as an application sandbox for any state objects that are allocated.

display

A Display pointer

Returns

A newly allocated Context

pub fn get_display(&self) -> Option<Display>

Retrieves the Display that is internally associated with the given self. This will return the same Display that was passed to Context::new or if None was passed to Context::new then this function returns a pointer to the display that was automatically setup internally.

Returns

The Display associated with the given self.

pub fn get_renderer(&self) -> Option<Renderer>

Retrieves the Renderer that is internally associated with the given self. This will return the same Renderer that was passed to Display::new or if None was passed to Display::new or Context::new then this function returns a pointer to the renderer that was automatically connected internally.

Returns

The Renderer associated with the given self.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Display for Context

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

Formats the value using the given formatter.

impl Hash for Context

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Context

fn cmp(&self, other: &Context) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: ObjectType> PartialEq<T> for Context

fn eq(&self, other: &T) -> 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<T: ObjectType> PartialOrd<T> for Context

fn partial_cmp(&self, other: &T) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for Context

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Context

impl IsA<Object> for Context
