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.

Empty

Empty geometry is not a raster.

Overflow

Size arithmetic overflow.

SourceChanged

Source declaration changed after preparation.

OutputLimit

Total encoded bytes exceed the supplied output allowance.

Patches

Layout requires unavailable or unannounced seek-back writes.

DestinationChanged

Destination access changed while policy was deciding.

RequestOrder

Encoder requests are out of order, inconsistent or outside the declaration.

Fields

pass: u32

Zero-based native pass named by the request.

first: u32

First requested row, or zero when rejecting a new pass.

PassLimit

The encoder exceeded its admitted native pass bound or final pass.

Fields

pass: u32

Zero-based native pass that could not be admitted.

IncompletePass

Completion or a new pass arrived before the current traversal completed.

Fields

pass: u32

Current or requested zero-based native pass; zero before any fill.

PullProtocol

A pull did not perform exactly one successful fill, or swallowed a failure.

ReplayChanged

Samples or identity changed on a repeated source/disk traversal.

Fields

pass: u32

Zero-based traversal on which a discrepancy was detected.

first: u32

Row whose digest differed, or the next row at an identity check.

EarlyOutput

Final-pass-only output appeared before its final traversal started.

Fields

pass: Option<u32>

Last started pass; None means output appeared before the first fill.

NoInputRoute

No executable input route could reserve its required managed storage.

Trait Implementations

impl Clone for Refusal

fn clone(&self) -> Refusal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Refusal

impl Debug for Refusal

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

Formats the value using the given formatter.

impl Display for Refusal

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

Formats the value using the given formatter.

impl Eq for Refusal

impl Error for Refusal

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 PartialEq for Refusal

fn eq(&self, other: &Refusal) -> bool

Equality operator ==.

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

Inequality operator !=.
