pub enum CommandLineFlag {
    A,
    E,
    L,
    N,
    P,
    X,
}

A command line option that affects parsing behavior.

Variants

A

E

-e: specifies a script to be executed.

L

-l: chomps the input line by default.

N

-n: wraps the script in a while gets loop.

P

-p: prints the value of $_ at the end of each loop.

X

-x: searches the input file for a shebang.

Trait Implementations

impl Clone for CommandLineFlag

fn clone(&self) -> CommandLineFlag

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CommandLineFlag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<CommandLineFlag> for u8

fn from(flag: CommandLineFlag) -> Self

Converts to this type from the input type.

impl Hash for CommandLineFlag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CommandLineFlag

fn eq(&self, other: &CommandLineFlag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
