Struct system_power_mode_config::SystemPowerModeConfig

pub struct SystemPowerModeConfig { /* private fields */ }

This library is used to parse a system power mode configuration JSON file into a data structure which also implements some convenience methods for accessing and consuming the data.

The intended usage is that SystemPowerModeConfig::read() is called with the path to a system power mode configuration JSON file. If successful, the function returns a SystemPowerModeConfig instance containing the parsed configuration.

The parser expects a a valid JSON5 serialization of SystemPowerModeConfig, such as the following:

  {
    clients: {
      wlan: {
        mode_matches: [
          {
            mode: 'battery_saver',
            level: 0,
          },
        ],
        default_level: 1,
      },
    },
  }

Represents the top level of a system power mode configuration.

This struct wraps the contents of a system power mode configuration file. All of the types contained within this top level struct are defined in the fuchsia.power.clientlevel and fuchsia.power.systemmode libraries.

Implementations

impl SystemPowerModeConfig

pub fn read(json_file_path: &Path) -> Result<SystemPowerModeConfig, Error>

Reads the supplied JSON file path and parses into a SystemPowerModeConfig instance.

Attempts to open, read, and parse the supplied JSON file into a valid SystemPowerModeConfig instance. If parsing was successful, then it is also tested for validity. If a SystemPowerModeConfig instance could not be created, or validation fails, then an error is returned.

pub fn validate(&self) -> Result<(), Error>

Validates the configuration.

pub fn get_client_config( &self, client_type: ClientType ) -> Option<&ClientConfig>

Gets the ClientConfig instance for the specified client.

pub fn into_iter(self) -> impl Iterator<Item = (ClientType, ClientConfig)>

Trait Implementations

impl Debug for SystemPowerModeConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SystemPowerModeConfig

fn eq(&self, other: &SystemPowerModeConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SystemPowerModeConfigTestExt for SystemPowerModeConfig

fn new() -> Self

Creates an empty SystemPowerModeConfig (no configured clients).

fn add_client_config( self, client_type: ClientType, config: ClientConfig ) -> Self

Adds a configuration entry for the specified client.
