Struct RexxValue 

pub struct RexxValue { /* private fields */ }

Every REXX value is a string. Numeric operations interpret the string content as a number when needed, and produce string results.

Implementations

impl RexxValue

pub fn new(s: impl Into<String>) -> Self

pub fn as_str(&self) -> &str

pub fn into_string(self) -> String

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn to_decimal(&self) -> Option<BigDecimal>

Attempt to interpret this value as a REXX number. REXX numbers can have leading/trailing blanks, optional sign, digits with an optional decimal point, and optional exponent.

pub fn is_number(&self) -> bool

Check if this value is a valid REXX number.

pub fn is_whole_number(&self, digits: u32) -> bool

REXX whole number check — a number with no fractional part within current NUMERIC DIGITS precision.

pub fn from_decimal(d: &BigDecimal, digits: u32, form: NumericForm) -> Self

Format a BigDecimal according to REXX numeric formatting rules. Respects NUMERIC DIGITS and NUMERIC FORM (SCIENTIFIC vs ENGINEERING).

Trait Implementations

impl Clone for RexxValue

fn clone(&self) -> RexxValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RexxValue

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

Formats the value using the given formatter.

impl Display for RexxValue

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

Formats the value using the given formatter.

impl From<&str> for RexxValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for RexxValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<i64> for RexxValue

fn from(n: i64) -> Self

Converts to this type from the input type.

impl Hash for RexxValue

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 RexxValue

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