Struct QueryItem 

#[non_exhaustive]
pub struct QueryItem<'a, H: Host, B: Behavior<H> + ?Sized> {
    pub behavior: &'a B,
    pub attachment: &'a H::Attachment,
}

Result of BehaviorSet::query().

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

behavior: &'a B

The found behavior’s current value.

attachment: &'a H::Attachment

The found behavior’s current attachment.

An attachment is additional data about “where” the behavior is attached to the host what part of the host should be affected by the behavior.

Trait Implementations

impl<H: Host, B: Behavior<H> + ?Sized> Clone for QueryItem<'_, H, B>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<H: Host, B: Behavior<H> + ?Sized> Debug for QueryItem<'_, H, B>

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

Formats the value using the given formatter.
