Struct precis_core::stringclasses::FreeformClass

pub struct FreeformClass {}

Concrete class representing PRECIS FreeformClass from RFC 8264.

Example

let ff = FreeformClass::default();
// character 𐍁 is OtherLetterDigits (R)
assert_eq!(ff.get_value_from_char('𐍁'), DerivedPropertyValue::SpecClassPval);
// Character S is ASCII7 (K)
assert_eq!(ff.get_value_from_char('S'), DerivedPropertyValue::PValid);
// Character 0x1170 is OldHangulJamo (I)
assert_eq!(ff.get_value_from_codepoint(0x1170), DerivedPropertyValue::Disallowed);

Trait Implementations

impl Clone for FreeformClass

fn clone(&self) -> FreeformClass

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FreeformClass

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

Formats the value using the given formatter.

impl Default for FreeformClass

fn default() -> FreeformClass

Returns the “default value” for a type.

impl PartialEq<FreeformClass> for FreeformClass

fn eq(&self, other: &FreeformClass) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SpecificDerivedPropertyValue for FreeformClass

fn on_has_compat(&self) -> DerivedPropertyValue

Callback invoked when the Unicode code point belongs to HasCompat

fn on_other_letter_digits(&self) -> DerivedPropertyValue

Callback invoked when the Unicode code point belongs to OtherLetterDigits

fn on_spaces(&self) -> DerivedPropertyValue

Callback invoked when the Unicode code point belongs to Spaces

fn on_symbols(&self) -> DerivedPropertyValue

Callback invoked when the Unicode code point belongs to Symbols

fn on_punctuation(&self) -> DerivedPropertyValue

Callback invoked when the Unicode code point belongs to Punctuation

impl StringClass for FreeformClass

fn get_value_from_char(&self, c: char) -> DerivedPropertyValue

Gets the derived property value according to the algorithm defined in rfc8264

fn get_value_from_codepoint(&self, cp: u32) -> DerivedPropertyValue

Gets the derived property value according to the algorithm defined in rfc8264

fn allows<S>(&self, label: S) -> Result<(), Error>where
    S: AsRef<str>,

Ensures that the string consists only of Unicode code points that are explicitly allowed by the PRECIS String Class
