Struct zebrad::commands::entry_point::EntryPoint

pub struct EntryPoint {
    pub cmd: Option<ZebradCmd>,
    pub config: Option<PathBuf>,
    pub verbose: bool,
    filters: Vec<String>,
}

Toplevel entrypoint command.

Handles obtaining toplevel help as well as verbosity settings.

Fields

cmd: Option<ZebradCmd>

Subcommand to execute.

The command option will delegate option parsing to the command type, starting at the first free argument. Defaults to start.

config: Option<PathBuf>

Path to the configuration file

verbose: bool

Increase verbosity setting

filters: Vec<String>

Filter strings which override the config file and defaults

Implementations

impl EntryPoint

pub fn cmd(&self) -> &ZebradCmd

Borrow the command in the option

Panics

If cmd is None

pub fn default_cmd_as_str() -> &'static str

Returns a string that parses to the default subcommand

fn should_add_default_subcommand(&self) -> bool

Checks if the provided arguments include a subcommand

pub fn process_cli_args(args: Vec<OsString>) -> Result<Vec<OsString>>

Process command arguments and insert the default subcommand if no subcommand is provided.
