Implementations

impl ArgumentsSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ArgumentsEvent, 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_string( &self, key: &str, ___deadline: MonotonicInstant, ) -> Result<Option<String>, Error>

Get the value of a boot argument key.

pub fn get_strings( &self, keys: &[String], ___deadline: MonotonicInstant, ) -> Result<Vec<Option<String>>, Error>

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

pub fn get_bool( &self, key: &str, defaultval: bool, ___deadline: MonotonicInstant, ) -> Result<bool, Error>

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], ___deadline: MonotonicInstant, ) -> Result<Vec<bool>, Error>

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, ___deadline: MonotonicInstant, ) -> Result<Vec<String>, Error>

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.
