Methods

impl nsIContentSniffer

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

Cast this nsIContentSniffer to one of its base interfaces.

/**
   * Given a chunk of data, determines a MIME type. Information from the given

   *
   * @param aRequest The request where this data came from. May be null.
   * @param aData Data to check
   * @param aLength Length of the data
   *
   * @return The content type
   *
   * @throw NS_ERROR_NOT_AVAILABLE if no MIME type could be determined.
   *
   * @note Implementations should consider the request read-only. Especially,
   * they should not attempt to set the content type property that subclasses of
   * nsIRequest might offer.

Trait Implementations

impl XpCom for nsIContentSniffer

const IID: nsIID

IID: nsIID = nsID(2776050971, 64611, 18782, [161, 105, 150, 232, 211, 49, 26, 240])

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 nsIContentSniffer

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIContentSniffer

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
