Enum FloatFormat 

pub enum FloatFormat {
    IeeeBigEndian,
    IbmHex,
}

Floating-point binary format for COMP-1/COMP-2 fields.

Copybooks define field usage but not the compiler’s concrete floating-point representation. This option makes the decode/encode interpretation explicit.

Examples

use copybook_options::FloatFormat;

let fmt = FloatFormat::default();
assert_eq!(fmt, FloatFormat::IeeeBigEndian);
assert_eq!(format!("{fmt}"), "ieee-be");

Variants

IeeeBigEndian

IEEE-754 big-endian binary format.

IbmHex

IBM hexadecimal floating-point format.

Trait Implementations

impl Clone for FloatFormat

fn clone(&self) -> FloatFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FloatFormat

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

Formats the value using the given formatter.

impl Default for FloatFormat

fn default() -> FloatFormat

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FloatFormat

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FloatFormat

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

Formats the value using the given formatter.

impl PartialEq for FloatFormat

fn eq(&self, other: &FloatFormat) -> 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 FloatFormat

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 FloatFormat

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

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.
