Enum Phase 

#[non_exhaustive]
pub enum Phase {
    Bind,
    Occur,
    Presence,
    Measure,
    Paginate,
    Suppress,
    Resolve,
    Emit,
    Fallback,
}

The phase in which a trace event was emitted.

Stability policy

Variants are added at the end of the enum to preserve existing tag strings. Renames or removals require a coordinated update across every consumer in the same change.

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.

Bind

Data binding — matching template subforms to dataset records.

Occur

Instance materialisation under occur.

Presence

Presence resolution (presence="visible|hidden|inactive|invisible").

Measure

Measurement of intrinsic content (text width/height).

Paginate

Pagination decisions (page break, defer, suppress).

Suppress

Page suppression (drop empty data-bound pages, etc.).

Resolve

SOM resolution.

Emit

Final emit/serialize step.

Fallback

Pipeline-level fallback: the XFA flatten path could not produce output and the caller has been served a non-XFA passthrough instead. Emitted from pdf-xfa::flatten when the inner XFA attempt errors or times out.

Implementations

impl Phase

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

Stable string tag; never rename without a taxonomy bump.

Trait Implementations

impl Clone for Phase

fn clone(&self) -> Phase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Phase

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

Formats the value using the given formatter.

impl Hash for Phase

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 Phase

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

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

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