pub struct ProviderSynchronousProxy { /* private fields */ }

Implementations

impl ProviderSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ProviderEvent, 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 get_typeface_by_id( &self, id: u32, ___deadline: MonotonicInstant, ) -> Result<ProviderGetTypefaceByIdResult, Error>

Get an exact font by asset ID. This would typically be called after ListTypefaces, e.g. as part of a font selection interface. As with fuchsia.fonts.GetTypeface, it is the caller’s responsibility to properly parse the file.

Possible errors: NOT_FOUND if no asset with the requested id exists. INTERNAL if the requested id exists, but the asset failed to load.

Eventually this should probably be folded into GetTypeface.

pub fn list_typefaces( &self, request: &ListTypefacesRequest, iterator: ServerEnd<ListTypefacesIteratorMarker>, ___deadline: MonotonicInstant, ) -> Result<ProviderListTypefacesResult, Error>

Creates a ListTypefacesIterator instance that will return a paginated list of fonts matching request.

Possible errors: INTERNAL if something bad happens.

pub fn get_typefaces_by_family( &self, family: &FamilyName, ___deadline: MonotonicInstant, ) -> Result<ProviderGetTypefacesByFamilyResult, Error>

Returns a TypefaceInfo for each font in the requested family. The results’ family fields will hold the canonical family name, even if this method is called with an alias.

This method should be called only if the caller knows family exists. Requesting a family that does not exist results in an error. To search for fonts by family name (or alias), use ListTypefaces instead.

Possible errors: NOT_FOUND if no family name or alias matches the requested family.
