interface nsISubstitutionObserver : nsISupports

Methods

impl nsISubstitutionObserver

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

Cast this nsISubstitutionObserver to one of its base interfaces.

impl nsISubstitutionObserver

pub unsafe fn OnSetSubstitution(
    &self,
    aRoot: &nsACString,
    aBaseURI: *const nsIURI
) -> nsresult

/**
     * To be called when a substition has been set or unset on a protocol
     * handler. Unset operations are identified by a null URI argument.
     *
     * @param aRoot the root key of the mapping
     * @param aBaseURI the base URI to be substituted for the root key by the
     *        protocol handler. For notifications triggered by unset
     *        operations (i.e., when is a substitution is removed from the
     *        protocol handler) this argument is null.
     */

Methods from Deref<Target = nsISupports>

Trait Implementations

impl XpCom for nsISubstitutionObserver

const IID: nsIID

IID: nsIID = nsID(1227657618, 14339, 20011, [131, 115, 210, 95, 229, 95, 85, 136])

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 nsISubstitutionObserver

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsISubstitutionObserver

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
