Methods

impl nsIResumableChannel

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

Cast this nsIResumableChannel to one of its base interfaces.

impl nsIResumableChannel

pub unsafe fn ResumeAt(
    &self,
    startPos: uint64_t,
    entityID: &nsACString
) -> nsresult

/**
     * Prepare this channel for resuming. The request will not start until
     * asyncOpen or open is called. Calling resumeAt after open or asyncOpen
     * has been called has undefined behaviour.
     *
     * @param startPos the starting offset, in bytes, to use to download
     * @param entityID information about the file, to match before obtaining
     *  the file. Pass an empty string to use anything.
     *
     * During OnStartRequest, this channel will have a status of
     *  NS_ERROR_NOT_RESUMABLE if the file cannot be resumed, eg because the
     *  server doesn't support this. This error may occur even if startPos
     *  is 0, so that the front end can warn the user.
     * Similarly, the status of this channel during OnStartRequest may be
     *  NS_ERROR_ENTITY_CHANGED, which indicates that the entity has changed,
     *  as indicated by a changed entityID.
     * In both of these cases, no OnDataAvailable will be called, and
     *  OnStopRequest will immediately follow with the same status code.

     * The entity id for this URI. Available after OnStartRequest.
     * @throw NS_ERROR_NOT_RESUMABLE if this load is not resumable.

Trait Implementations

impl XpCom for nsIResumableChannel

const IID: nsIID

IID: nsIID = nsID(1255225082, 33711, 18978, [167, 110, 80, 54, 66, 192, 244, 168])

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 nsIResumableChannel

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIResumableChannel

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
