Validation Method

Variants

Basic

… to indicate that the value(s) should simply match the field type and datatype constraints, the <validate/> element shall contain a <basic/> child element. Using <basic/> validation, the form interpreter MUST follow the validation rules of the datatype (if understood) and the field type.

https://xmpp.org/extensions/xep-0122.html#usercases-validation.basic

Open

For “list-single” or “list-multi”, to indicate that the user may enter a custom value (matching the datatype constraints) or choose from the predefined values, the <validate/> element shall contain an <open/> child element. The <open/> validation method applies to “text-multi” differently; it hints that each value for a “text-multi” field shall be validated separately. This effectively turns “text-multi” fields into an open-ended “list-multi”, with no options and all values automatically selected.

https://xmpp.org/extensions/xep-0122.html#usercases-validation.open

Range

To indicate that the value should fall within a certain range, the <validate/> element shall contain a <range/> child element. The ‘min’ and ‘max’ attributes of the <range/> element specify the minimum and maximum values allowed, respectively.

The ‘max’ attribute specifies the maximum allowable value. This attribute is OPTIONAL. The value depends on the datatype in use.

The ‘min’ attribute specifies the minimum allowable value. This attribute is OPTIONAL. The value depends on the datatype in use.

The <range/> element SHOULD possess either a ‘min’ or ‘max’ attribute, and MAY possess both. If neither attribute is included, the processor MUST assume that there are no range constraints.

Fields

min: Option<String>

The ‘min’ attribute specifies the minimum allowable value.

max: Option<String>

The ‘max’ attribute specifies the maximum allowable value.

Regex(String)

To indicate that the value should be restricted to a regular expression, the <validate/> element shall contain a <regex/> child element. The XML character data of this element is the pattern to apply. The syntax of this content MUST be that defined for POSIX extended regular expressions, including support for Unicode. The <regex/> element MUST contain character data only.

Trait Implementations

impl Clone for Method

fn clone(&self) -> Method

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Method

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

Formats the value using the given formatter.

impl From<Method> for Element

fn from(value: Method) -> Self

Converts to this type from the input type.

impl PartialEq for Method

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

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

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 TryFrom<Element> for Method

type Error = Error

The type returned in the event of a conversion error.

fn try_from(elem: Element) -> Result<Self, Self::Error>

Performs the conversion.
