Implementations

impl Config

pub fn new() -> WallSwitchResult<Self>

Read command line arguments with priority order:

1. read config file || read default config
2. set_command_line_arguments
3. validate_config
4. write_config_file

At the end add or update config file.

pub fn in_range(&self, value: u64) -> bool

Check if the value is in the range.

pub fn print(&self) -> WallSwitchResult<()>

Print Config.

pub fn validate_config(self) -> WallSwitchResult<Self>

Validate configuration

pub fn write_config_file( self, path: &PathBuf, read_default_config: bool, ) -> WallSwitchResult<Self>

Write config file path:: “/home/user_name/.config/wallswitch/wallswitch.json”

pub fn get_number_of_images(&self) -> usize

Get the number of images per cycle
