Trait query_interface::Object

pub unsafe trait Object: Any { }

This trait is the primary function of the library. Object trait objects can be freely queried for any other trait, allowing conversion between trait objects.

Methods

impl Object

fn query_ref<U: Any + ?Sized>(&self) -> Option<&U>

fn query_mut<U: Any + ?Sized>(&mut self) -> Option<&mut U>

fn query<U: Any + ?Sized>(self: Box<Self>) -> Result<Box<U>, Box<Self>>

fn obj_partial_eq(&self, other: &Self) -> bool

fn obj_partial_cmp(&self, other: &Self) -> Option<Ordering>

Trait Implementations

impl ToOwned for Object

type Owned = Box<Object>

fn to_owned(&self) -> Box<Object>

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

🔬 This is a nightly-only experimental API. (toowned_clone_into)

recently added

Uses borrowed data to replace owned data, usually by cloning.

impl Debug for Object

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

Formats the value using the given formatter.

impl PartialEq for Object

fn eq(&self, other: &Self) -> 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 !=.

impl Eq for Object

impl PartialOrd for Object

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Ord for Object

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

This method returns an Ordering between self and other.

impl Hash for Object

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, 

Feeds a slice of this type into the given [Hasher].
