Struct HandleCollection 

pub struct HandleCollection { /* private fields */ }

Represents a collection of uniquely named Handles.

Implementations

impl HandleCollection

pub fn contains(&self, name: &str) -> bool

Reports whether this collection contains a Handle with the given unique name.

pub fn get(&self, name: &str) -> Option<&Handle>

Retrieves Some reference to a Handle from this collection under the given name, or None, if the name is not present in the collection.

pub fn expect(&self, name: &str) -> &Handle

Retrieves a reference to a Handle from this collection under the given name. Panics if the name is not present in the collection.

Trait Implementations

impl AsRef<HandleCollection> for HandleCollection

fn as_ref(&self) -> &HandleCollection

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for HandleCollection

fn clone(&self) -> HandleCollection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandleCollection

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

Formats the value using the given formatter.

impl Default for HandleCollection

fn default() -> HandleCollection

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HandleCollection

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<const N: usize, S> From<[(S, Handle); N]> for HandleCollection

where S: Into<Slug>,

fn from(value: [(S, Handle); N]) -> Self

Converts to this type from the input type.

impl<S> FromIterator<(S, Handle)> for HandleCollection

where S: Into<Slug>,

fn from_iter<T: IntoIterator<Item = (S, Handle)>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for HandleCollection

fn eq(&self, other: &HandleCollection) -> 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.
