Struct structopt_flags::LogLevelOpt

pub struct LogLevelOpt { /* private fields */ }

This struct provides the --log and -L cli option

By default, the log level is set to info.

    Self: Sized,
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString> + Clone,

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error>where
    Self: Sized,
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString> + Clone,

Gets the struct from any iterator such as a Vec of your making.
