[−][src]Struct structopt_flags::ConfigFileNoDef
This struct provides the --config_file
cli option
The option is no mandatory, but a default value can be provided wit the get_with_default()
extern crate structopt_flags; #[macro_use] extern crate structopt; use structopt::StructOpt; use structopt_flags::GetWithDefault; // to access get_log_level use std::path::PathBuf; #[derive(Debug, StructOpt)] #[structopt(name = "config-file", about = "An example using config_file option")] struct Opt { #[structopt(flatten)] config: structopt_flags::ConfigFileNoDef, } fn main() { let opt = Opt::from_args(); let config_file = opt.config.get_with_default("config-file.toml"); // use the config file }
