Struct FontResolverProxy

pub struct FontResolverProxy { /* private fields */ }

Implementations

impl FontResolverProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.pkg/FontResolver.

pub fn take_event_stream(&self) -> FontResolverEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn resolve( &self, package_url: &str, directory_request: ServerEnd<DirectoryMarker>, ) -> QueryResponseFut<FontResolverResolveResult, DefaultFuchsiaResourceDialect>

Populates or updates the cache of a font package, fetching it if it is not present on the local system.

• request package_url the package URL of a font package.
• request directory_request a request for a directory that will be resolved when the package has been successfully cached. The directory should contain a single file, corresponding to the asset filename. The client should retain the directory handle for as long as needed to prevent the package from being evicted from cache.

• error a zx_status value indicating failure. One of the following:
  • ZX_ERR_ACCESS_DENIED if the resolver does not have permission to fetch a package blob.
  • ZX_ERR_IO if there is some other unspecified error during I/O.
  • ZX_ERR_NOT_FOUND if the font package or a package blob does not exist, or is not known to be a font package.
  • ZX_ERR_NO_SPACE if there is no space available to store the package.
  • ZX_ERR_UNAVAILABLE if the resolver is currently unable to fetch a package blob.
