XfaError.

Variants

LoadFailed(String)

LoadFailed.

PacketNotFound(String)

PacketNotFound.

Encrypted(String)

Encrypted.

XmlParse(String)

XmlParse.

FontError(String)

FontError.

LayoutError(String)

LayoutError.

LayoutFailed(String)

LayoutFailed.

ParseFailed(String)

ParseFailed.

FormCalcError(String)

FormCalcError.

Io(Error)

Io.

RenderingPolicyUnsupported(String)

RenderingPolicyUnsupported. D11. The requested crate::flatten::XfaRenderingPolicy is not available in the calling context (e.g. a future/unknown policy, or a command such as flatten that applies SavedStateFaithful only). Both SavedStateFaithful (the default, production policy) and FreshMergeExperimental (experimental, opt-in) are implemented as of D12; this variant exists so an unavailable policy fails loudly rather than silently producing default output under the wrong label.

ExtractionFailed(String)

XFA packet extraction failed (e.g. missing /AcroForm, corrupt stream).

TemplateParse(String)

Template XML could not be parsed.

BindingFailed(String)

Data binding from datasets to template failed.

LayoutFailedAt

LayoutFailedAt. LayoutFailedAt. Layout failed at a specific pipeline stage.

Use this variant when you can identify which stage (e.g. “paginate”, “split”, “occur”) caused the failure so callers can give better diagnostics.

Fields

stage: String

Pipeline stage where layout failed.

reason: String

Reason for the failure.

RenderFailed(String)

PDF content stream generation failed.

FlattenFailed(String)

Final PDF serialisation / flatten step failed.

UnsupportedFeature(String)

Feature is intentionally unsupported by the non-interactive XFA engine.

UnsupportedHostCapability

XFA-JS-HOST-STUBS — A script reached a host capability that requires genuine user / viewer interaction (e.g. xfa.host.messageBox, xfa.host.openList, xfa.signature.sign). The flatten pipeline runs non-interactively, so the call cannot be satisfied honestly. Inside the sandbox the call is short-circuited to a safe default and counted in crate::DynamicScriptOutcome::js_unsupported_host_calls; this error variant exists for synchronous Rust API surfaces that want to surface the gap to embedding callers rather than silently absorb it.

The capability string is a stable, well-known identifier such as "xfa.host.messageBox" and is suitable for inclusion in diagnostics.

Fields

capability: String

Stable identifier of the host capability that was requested.

Trait Implementations

impl Debug for XfaError

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

Formats the value using the given formatter.

impl Display for XfaError

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

Formats the value using the given formatter.

impl Error for XfaError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for XfaError

fn from(source: Error) -> XfaError

Converts to this type from the input type.
