Implementations

impl ItemsSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ItemsEvent, 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( &self, type_: u32, extra: u32, ___deadline: MonotonicInstant, ) -> Result<(Option<Vmo>, u32), Error>

Get a payload for a boot item of type and extra. NOTE: We return the length of the item, as VMOs must be page-aligned.

TODO: Refactor API: https://fxbug.dev/42109921

For a list of types, refer to <lib/zbi-format/zbi.h>. For a list of extras, refer to <lib/zbi-format/driver-config.h>.

pub fn get2( &self, type_: u32, extra: Option<&Extra>, ___deadline: MonotonicInstant, ) -> Result<ItemsGet2Result, Error>

Get all stored items of type, optionally also restricted by extra. Note that length is returned for each item as VMOs are page-aligned.

Returns ZX_ERR_NOT_SUPPORTED if this is an untracked item which will never be stored.

pub fn get_bootloader_file( &self, filename: &str, ___deadline: MonotonicInstant, ) -> Result<Option<Vmo>, Error>

Gets the payload for a ZBI_TYPE_BOOTLOADER_FILE boot item. Note: ZX_PROP_VMO_CONTENT_SIZE will be set to the actual file content size
