Struct PolylineId 

pub struct PolylineId { /* private fields */ }

Handle to a pre-uploaded polyline produced by DeviceResources::upload_polyline.

Implementations

impl PolylineId

pub const INVALID: PolylineId

A handle that refers to nothing. Store lookups always return None for it. Use it as the default / placeholder value where a real resource has not been assigned yet.

pub fn index(&self) -> usize

The raw slot index this handle points at. Used to index parallel per-slot arrays; not meaningful for INVALID.

Trait Implementations

impl Clone for PolylineId

fn clone(&self) -> PolylineId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContentHandle for PolylineId

const INVALID: Self = PolylineId::INVALID

The handle value that refers to nothing. Store lookups always return None for it.

fn index(&self) -> usize

The raw slot index this handle points at.

fn generation(&self) -> u32

The generation this handle was issued against.

fn from_parts(index: u32, generation: u32) -> Self

Build a handle from a raw slot index and generation. The store mints a handle this way on insert; outside code obtains handles from upload calls and treats them as opaque.

fn is_valid(&self) -> bool

Whether this handle is anything other than INVALID. A valid handle may still fail to resolve if its slot was freed.

impl Copy for PolylineId

impl Debug for PolylineId

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

Formats the value using the given formatter.

impl Eq for PolylineId

impl Hash for PolylineId

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 PolylineId

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