Struct Args 

pub struct Args { /* private fields */ }

Safe view over a builtin’s (argc, argv). argv[0] is the command name.

Implementations

impl Args

pub unsafe fn from_raw(argc: usize, argv: *const *const c_char) -> Self

Decode a raw (argc, argv) pair into owned Strings.

Safety

argv must point to argc valid, NUL-terminated C strings, as guaranteed by the host when it invokes a BuiltinFn.

pub fn name(&self) -> &str

The command name (argv[0]), or "" if somehow empty.

pub fn rest(&self) -> &[String]

The positional arguments (everything after argv[0]).

pub fn to_vec(&self) -> &[String]

All of argv, name included.
