pub trait ArgsExt: IntoIterator<Item = String> + Sized {
// Provided method
fn opts(self, short_pairs: &str) -> Result<Parser, NonAlphaNumError> { ... }
}Provided Methods§
Sourcefn opts(self, short_pairs: &str) -> Result<Parser, NonAlphaNumError>
fn opts(self, short_pairs: &str) -> Result<Parser, NonAlphaNumError>
Parses an Iterator using Parser.
Returns None if short_pairs has non-alphanumeric characters.
§Examples
$ program arg1 -abcx12 -y 3 --long --key=value - arg2 -- -kh --ignoreThe following code simulates parsing of the command above:
use argsyn::ArgsExt;
let cmd = "program arg1 -abcx12 -y 3 --long --key=value - arg2 -- -kh --ignore";
let args = cmd
.split_ascii_whitespace()
.into_iter()
.map(|s| s.to_string());
for opt in args.opts("xy").unwrap() {
println!("{:?}", opt);
}Running the above code produces the following output:
NonOption("program")
NonOption("arg1")
Short("a")
Short("b")
Short("c")
ShortPair("x", "12")
ShortPair("y", "3")
Long("long")
LongPair("key", "value")
Dash
NonOption("arg2")
Terminator
NonOption("-kh")
NonOption("--ignore")Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
