impl Visitor<'_> for MonetaryValueVisitor

Source§

fn visit_str<E>(self, value: &str) -> Result<Self::Value, E>
where E: Error,

We’re wanting to deserialize a MonetaryValue from a string that can be in a Ticker Style format. It could be beneficial to support multiple formats for convenience due to different localizations of the world. This would allow for maximum flexibility in representation. This does mean that the numerical format can be wide and varied. This does not mean that this format does not come without restrictions.

A list of parsing restrictions:

  • The value’s numerical representation is expected to be formatting using arabic numerals.
  • The value’s numerical representation must have the expected number of significant digits of the currency determined by the currency code.
  • The currency code and the numerical value MUST be separated by a non-breaking space character.
  • The Currency Code cannot have numeric digits within it.
  • The Currency Code must be a valid ISO 4217 Currency Code for all fiat currencies.
  • The Currency Code may be a valid Crypto Currency Identifier
  • The Currency Code may be a valid Token Identifier
  • The Currency Code MUST be at least 3 characters long.

This means that his function should be able to support parsing the following representations:

§Supported Representations
  • USD 0.00
  • USD 0,00
  • USD 0 00
  • USD 0
  • 0.00 USD
  • 0,00 USD
