Enum NodeKind 

#[non_exhaustive]
pub enum NodeKind {
    Root,
    PageSet,
    PageArea,
    ContentArea,
    Subform,
    SubformSet,
    Field,
    Draw,
    ExclGroup,
    Other,
}

Kind of a layout node in the IR.

Other covers anything we don’t classify yet; it intentionally does not carry payload because v1 of the IR aims for a closed, reviewable enum.

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.

Root

The root sentinel of the layout tree.

PageSet

pageSet container.

PageArea

pageArea container.

ContentArea

contentArea container.

Subform

subform container.

SubformSet

subformSet container.

Field

Form field.

Draw

draw (static decoration).

ExclGroup

exclGroup (radio-button-like exclusive group).

Other

Anything not yet classified.

Implementations

impl NodeKind

pub fn tag(self) -> &'static str

Stable string tag used in canonical JSON output.

Trait Implementations

impl Clone for NodeKind

fn clone(&self) -> NodeKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeKind

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

Formats the value using the given formatter.

impl Default for NodeKind

fn default() -> NodeKind

Returns the “default value” for a type.

impl Ord for NodeKind

fn cmp(&self, other: &NodeKind) -> 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 NodeKind

fn eq(&self, other: &NodeKind) -> 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 NodeKind

fn partial_cmp(&self, other: &NodeKind) -> 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.
