Implementations

impl FontResolverSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<FontResolverEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn resolve( &self, package_url: &str, directory_request: ServerEnd<DirectoryMarker>, ___deadline: MonotonicInstant, ) -> Result<FontResolverResolveResult, Error>

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.
