interface nsIExpandedPrincipal : nsISupports

/**
 * If SystemPrincipal is too risky to use, but we want a principal to access
 * more than one origin, ExpandedPrincipals letting us define an array of
 * principals it subsumes. So script with an ExpandedPrincipals will gain
 * same origin access when at least one of its principals it contains gained
 * sameorigin acccess. An ExpandedPrincipal will be subsumed by the system
 * principal, and by another ExpandedPrincipal that has all its principals.
 * It is added for jetpack content-scripts to let them interact with the
 * content and a well defined set of other domains, without the risk of
 * leaking out a system principal to the content. See: Bug 734891

Trait Implementations

impl XpCom for nsIExpandedPrincipal

const IID: nsIID

IID: nsIID = nsID(4091639775, 27230, 18591, [128, 167, 45, 209, 72, 20, 113, 216])

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 nsIExpandedPrincipal

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIExpandedPrincipal

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
