Enum IcmsVariant 

#[non_exhaustive]
pub enum IcmsVariant {
    Cst(Box<IcmsCst>),
    Csosn(Box<IcmsCsosn>),
}

Unified ICMS variant wrapping both normal-regime CSTs and Simples Nacional CSOSNs. Pass one of these to build_icms_xml for compile-time-safe XML generation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cst(Box<IcmsCst>)

Normal tax regime (Lucro Real / Presumido).

Csosn(Box<IcmsCsosn>)

Simples Nacional tax regime (CRT 1/2).

Trait Implementations

impl Clone for IcmsVariant

fn clone(&self) -> IcmsVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IcmsVariant

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

Formats the value using the given formatter.

impl From<IcmsCsosn> for IcmsVariant

fn from(csosn: IcmsCsosn) -> Self

Converts to this type from the input type.

impl From<IcmsCst> for IcmsVariant

fn from(cst: IcmsCst) -> Self

Converts to this type from the input type.

impl TaxCalculation for IcmsVariant

fn build_xml(&self) -> String

Build the ICMS XML string, delegating to build_icms_xml.

A throwaway crate::tax_icms::IcmsTotals accumulator is used since the trait cannot surface totals side-effects. Returns an empty string if the underlying call returns an error.
