A resource limit was exceeded.

Returned by ResourceLimits::check_dimensions() and related methods. Each variant carries the actual value and the limit that was exceeded, enabling useful error messages.

Implements core::error::Error so codecs can wrap it in their own error types.

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.

Implementations

impl LimitExceeded

pub fn kind(&self) -> LimitKind

Which cap was exceeded, without the actual/max values — for coarse routing via ErrorCategory.

Trait Implementations

impl CategorizedError for LimitExceeded

fn codec_name(&self) -> Option<&'static str>

The originating codec’s name (e.g. Some("zenjpeg")). A codec returns a constant here on its error type so CodecError::from_native / of can tag the envelope from the value — no separate argument. Required: there is deliberately no default, so every implementor must answer it. The zencodec cause types (LimitExceeded, UnsupportedOperation, enough::StopReason) implement it as None since they aren’t codecs.

fn category(&self) -> ErrorCategory

This error’s coarse ErrorCategory.

impl Clone for LimitExceeded

fn clone(&self) -> LimitExceeded

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LimitExceeded

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

Formats the value using the given formatter.

impl Display for LimitExceeded

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

Formats the value using the given formatter.

impl Eq for LimitExceeded

impl Error for LimitExceeded

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 LimitExceeded

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

Equality operator ==.

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

Inequality operator !=.
