Struct SourceID 

pub struct SourceID { /* private fields */ }

Represents a unique ID out of a linked list of DataID. Taken together, all the IDs in a program form a tree that doesn’t just ensure uniqueness, but also allows tracking the structure of the data being used and how each piece of data depends on another piece of data. As a result, the tree structure of IDs generally diverges from the component tree of the actual UI, and may or may not actually resemble the storage structure of the data.

Implementations

impl SourceID

pub fn child(self: &Arc<Self>, id: DataID) -> Arc<Self>

Creates a new SourceID out of the given DataID, with ourselves as its parent

pub fn duplicate(self: &Arc<Self>) -> Arc<Self>

Creates a new, unique duplicate ID using this as the parent and the strong count of this Rc as the child DataID. This is used to enable cloning certain components, like component::shape::Shape, while automatically generating a new unique ID for the cloned component.

Trait Implementations

impl Clone for SourceID

fn clone(&self) -> SourceID

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceID

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

Formats the value using the given formatter.

impl Default for SourceID

fn default() -> SourceID

Returns the “default value” for a type.

impl Display for SourceID

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

Formats the value using the given formatter.

impl Hash for SourceID

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 PartialEq for SourceID

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