Enum ZeroSignPolicy 

pub enum ZeroSignPolicy {
    Positive,
    Preferred,
}

Policy for the sign zone nibble when the numeric value is exactly zero.

COBOL compilers differ on whether zero is positive (0xC0) or unsigned (0xF0). This enum lets callers choose the convention.

Examples

use copybook_overpunch::ZeroSignPolicy;

let policy = ZeroSignPolicy::Preferred;
assert_eq!(policy, ZeroSignPolicy::Preferred);
assert_ne!(policy, ZeroSignPolicy::Positive);

Variants

Positive

Use positive sign for zero (C for EBCDIC, ‘{’ for ASCII)

Preferred

Use ‘F’ sign for zero in EBCDIC, positive in ASCII

Trait Implementations

impl Clone for ZeroSignPolicy

fn clone(&self) -> ZeroSignPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZeroSignPolicy

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

Formats the value using the given formatter.

impl PartialEq for ZeroSignPolicy

fn eq(&self, other: &ZeroSignPolicy) -> 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.
