Methods

impl mozIRepresentativeColorCallback

pub fn coerce<T: mozIRepresentativeColorCallbackCoerce>(&self) -> &T

Cast this mozIRepresentativeColorCallback to one of its base interfaces.

impl mozIRepresentativeColorCallback

pub unsafe fn OnComplete(&self, success: bool, color: uint32_t) -> nsresult

/**
   * Will be called when color analysis finishes.
   *
   * @param success
   *        True if analysis was successful, false otherwise.
   *        Analysis can fail if the image is transparent, imageURI doesn't
   *        resolve to a valid image, or the image is too big.
   *
   * @param color
   *        The representative color as an integer in RGB form.
   *        e.g. 0xFF0102 == rgb(255,1,2)
   *        If success is false, color is not provided.

Trait Implementations

impl XpCom for mozIRepresentativeColorCallback

const IID: nsIID

IID: nsIID = nsID(3825770017, 29110, 16559, [181, 70, 51, 194, 27, 144, 232, 116])

fn query_interface<T: XpCom>(&self) -> Option<RefPtr<T>>

Perform a QueryInterface call on this object, attempting to dynamically cast it to the requested interface type. Returns Some(RefPtr) if the cast succeeded, and None otherwise.

impl RefCounted for mozIRepresentativeColorCallback

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for mozIRepresentativeColorCallback

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
