Enum FieldCategory 

pub enum FieldCategory {
    Flat,
    Attribute,
    Element,
    Text,
    Tag,
    Elements,
}

Category of a field for format-aware field lookup.

For flat formats (JSON, TOML, YAML), all fields are Flat. For DOM formats (XML, HTML), fields are categorized by their role in the tree structure.

Variants

Flat

Regular field in flat formats (JSON, TOML, YAML, etc.) All fields are treated as simple key-value pairs.

Attribute

Field is an attribute (#[facet(attribute)], xml::attribute, html::attribute)

Element

Field is a child element (default for DOM structs, or explicit xml::element)

Text

Field captures text content (xml::text, html::text)

Tag

Field captures the tag name (xml::tag, html::tag)

Elements

Field captures all unmatched children (xml::elements)

Implementations

impl FieldCategory

pub fn from_field_dom(field: &Field) -> Option<Self>

Determine the DOM category of a field based on its attributes.

Returns None for flattened fields (they don’t have a single category). For non-DOM contexts, use FieldCategory::Flat directly.

Trait Implementations

impl Clone for FieldCategory

fn clone(&self) -> FieldCategory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldCategory

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

Formats the value using the given formatter.

impl Default for FieldCategory

fn default() -> FieldCategory

Returns the “default value” for a type.

impl Hash for FieldCategory

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 Ord for FieldCategory

fn cmp(&self, other: &FieldCategory) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FieldCategory

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

impl PartialOrd for FieldCategory

fn partial_cmp(&self, other: &FieldCategory) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
