Enum ZonedEncodingFormat 

pub enum ZonedEncodingFormat {
    Ascii,
    Ebcdic,
    Auto,
}

Zoned decimal encoding format (ASCII, EBCDIC, or auto-detect). Zoned decimal encoding format specification for round-trip fidelity.

This enum controls how zoned decimal fields are encoded and decoded, enabling preservation of the original encoding format during round-trip operations for enterprise data consistency.

Examples

use copybook_zoned_format::ZonedEncodingFormat;

let fmt = ZonedEncodingFormat::default();
assert!(fmt.is_auto());
assert_eq!(fmt.description(), "Automatic detection based on zone nibbles");

let detected = ZonedEncodingFormat::detect_from_byte(0xF5);
assert_eq!(detected, Some(ZonedEncodingFormat::Ebcdic));

Variants

Ascii

ASCII digit zones (0x30-0x39).

Ebcdic

EBCDIC digit zones (0xF0-0xF9).

Auto

Automatic detection based on zone nibbles.

Implementations

impl ZonedEncodingFormat

pub const fn is_ascii(self) -> bool

Check if this is ASCII encoding.

pub const fn is_ebcdic(self) -> bool

Check if this is EBCDIC encoding.

pub const fn is_auto(self) -> bool

Check if this is auto-detection mode.

pub const fn description(self) -> &'static str

Get a human-readable description of the encoding format.

pub fn detect_from_byte(byte: u8) -> Option<ZonedEncodingFormat>

Detect encoding format from a single byte of zoned decimal data.

Examines the zone nibble (upper 4 bits) to determine the encoding format. Returns None for invalid zone values.

Trait Implementations

impl Clone for ZonedEncodingFormat

fn clone(&self) -> ZonedEncodingFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZonedEncodingFormat

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

Formats the value using the given formatter.

impl Default for ZonedEncodingFormat

fn default() -> ZonedEncodingFormat

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ZonedEncodingFormat

fn deserialize<__D>( __deserializer: __D, ) -> Result<ZonedEncodingFormat, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ZonedEncodingFormat

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

Formats the value using the given formatter.

impl PartialEq for ZonedEncodingFormat

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

impl Serialize for ZonedEncodingFormat

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ValueEnum for ZonedEncodingFormat

fn value_variants<'a>() -> &'a [ZonedEncodingFormat]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
