Struct ArgumentsProxy

pub struct ArgumentsProxy { /* private fields */ }

Implementations

impl ArgumentsProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.boot/Arguments.

pub fn take_event_stream(&self) -> ArgumentsEventStream

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

Panics

Panics if the event stream was already taken.

pub fn get_string( &self, key: &str, ) -> QueryResponseFut<Option<String>, DefaultFuchsiaResourceDialect>

Get the value of a boot argument key.

pub fn get_strings( &self, keys: &[String], ) -> QueryResponseFut<Vec<Option<String>>, DefaultFuchsiaResourceDialect>

Get the values of a list of arguments specified in keys.

pub fn get_bool( &self, key: &str, defaultval: bool, ) -> QueryResponseFut<bool, DefaultFuchsiaResourceDialect>

Get the boolean value of a boot argument keys, or return defaultval if the argument is not present. A key is considered to be false if its string value is exactly “off”, “0”, or “false”. Any other value (including empty) is returned as true.

pub fn get_bools( &self, keys: &[BoolPair], ) -> QueryResponseFut<Vec<bool>, DefaultFuchsiaResourceDialect>

Get the boolean values of a list of boot arguments keys.key, or return keys.defaultval for each if not present.

pub fn collect( &self, prefix: &str, ) -> QueryResponseFut<Vec<String>, DefaultFuchsiaResourceDialect>

Get all boot arguments with keys starting with prefix. Returns a vector with strings of the form ‘key=value’. TODO(https://fxbug.dev/42108659) - remove Collect once boot arguments have been componentised.

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
