[−][src]Function argh::cargo_from_env
pub fn cargo_from_env<T: TopLevelCommand>() -> T
Create a FromArgs
type from the current process's env::args
.
This special cases usages where argh is being used in an environment where cargo is driving the build. We skip the second env variable.
This function will exit early from the current process if argument parsing
was unsuccessful or if information like --help
was requested.
