Struct RuntimeMetadata 

pub struct RuntimeMetadata {
    pub executed: usize,
    pub runtime_errors: usize,
    pub timeouts: usize,
    pub oom: usize,
    pub host_calls: usize,
    pub mutations: usize,
    pub instance_writes: usize,
    pub list_writes: usize,
    pub binding_errors: usize,
    pub resolve_failures: usize,
    pub data_reads: usize,
}

Cumulative metadata for a single document’s flatten. The runtime adapter accumulates counters across calls; the dispatch site reads them via XfaJsRuntime::take_metadata when the document is done.

Fields

executed: usize

Scripts that ran to completion inside the sandbox.

runtime_errors: usize

Generic runtime / script errors (parse, throw, NoBindings, …).

timeouts: usize

Time-budget exhaustions.

oom: usize

Memory-budget exhaustions.

host_calls: usize

Phase C host-binding invocations.

mutations: usize

Phase C successful field.rawValue writes.

instance_writes: usize

Phase D successful instanceManager structure writes.

list_writes: usize

Phase D-β successful listbox clearItems / addItem writes.

binding_errors: usize

Phase C binding-level failures (type, activity, cap, parse).

resolve_failures: usize

Phase C SOM resolution misses / failures.

data_reads: usize

Phase D-γ successful DataDom reads (children / value / child-by-name).

Implementations

impl RuntimeMetadata

pub fn is_clean(&self) -> bool

True when the runtime never reported any error class.

pub fn accumulate(&mut self, other: RuntimeMetadata)

Add another metadata snapshot into this one.

Trait Implementations

impl Clone for RuntimeMetadata

fn clone(&self) -> RuntimeMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeMetadata

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

Formats the value using the given formatter.

impl Default for RuntimeMetadata

fn default() -> RuntimeMetadata

Returns the “default value” for a type.

impl PartialEq for RuntimeMetadata

fn eq(&self, other: &RuntimeMetadata) -> 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 Copy for RuntimeMetadata
