Function safecoin_clap_utils::keypair::keypair_from_path
source · pub fn keypair_from_path(
matches: &ArgMatches<'_>,
path: &str,
keypair_name: &str,
confirm_pubkey: bool
) -> Result<Keypair, Box<dyn Error>>
Expand description
Loads a Keypair from one of several possible sources.
The path
is not strictly a file system path, but is interpreted as various
types of signing source, depending on its format, one of which is a path
to a keypair file. Some sources may require user interaction in the course
of calling this function.
This is the same as signer_from_path
except that it only supports
signing sources that can result in a Keypair: prompt for seed phrase,
keypair file, and stdin.
If confirm_pubkey
is true
then after deriving the pubkey, the user will
be prompted to confirm that the pubkey is as expected.
See signer_from_path
for full documentation of how this function
interprets its arguments.
Examples
use clap::{App, Arg, value_t_or_exit};
use safecoin_clap_utils::keypair::keypair_from_path;
let clap_app = App::new("my-program")
// The argument we'll parse as a signer "path"
.arg(Arg::with_name("keypair")
.required(true)
.help("The default signer"));
let clap_matches = clap_app.get_matches();
let keypair_str = value_t_or_exit!(clap_matches, "keypair", String);
let signer = keypair_from_path(
&clap_matches,
&keypair_str,
"keypair",
false,
)?;
