Struct webrender_api::DocumentId

#[repr(C)]
pub struct DocumentId {
    pub namespace_id: IdNamespace,
    pub id: u32,
}

A key uniquely identifying a WebRender document.

Instances can manage one or several documents (using the same render backend thread). Each document will internally correspond to a single scene, and scenes are made of one or several pipelines.

Fields

namespace_id: IdNamespace

id: u32

Methods

impl DocumentId

pub fn new(namespace_id: IdNamespace, id: u32) -> Self

pub const INVALID: DocumentId

Trait Implementations

impl Clone for DocumentId

fn clone(&self) -> DocumentId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for DocumentId

impl Debug for DocumentId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DocumentId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Eq for DocumentId

impl Hash for DocumentId

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].

impl MallocSizeOf for DocumentId

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq<DocumentId> for DocumentId

fn eq(&self, other: &DocumentId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &DocumentId) -> bool

This method tests for !=.

impl Peek for DocumentId

unsafe fn peek_from(bytes: *const u8, output: *mut Self) -> *const u8

Deserialize from the buffer pointed to by bytes.

impl Poke for DocumentId

fn max_size() -> usize

Return the maximum number of bytes that the serialized version of Self will occupy.

unsafe fn poke_into(&self, bytes: *mut u8) -> *mut u8

Serialize into the buffer pointed to by bytes.

impl Serialize for DocumentId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer,
