Variants

ParseError

Error during the parsing phase (nom).

Fields

line: usize

Line number where the error occurred.

message: String

Description of the parse failure.

InstructionError(String)

Error building instructions from commands.

BackendError(String)

Error specific to a rendering backend (PNG, PDF, etc).

FontError(String)

Error related to font loading or registration.

EmptyInput

Input ZPL was empty or only contained whitespace.

ImageError(String)

Errors related to image decoding (Base64 or binary).

SecurityLimitExceeded(String)

Security limit reached (e.g., OOM protection).

Unexpected(String)

Generic unexpected error.

Trait Implementations

impl Debug for ZplError

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

Formats the value using the given formatter.

impl Display for ZplError

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

Formats the value using the given formatter.

impl Error for ZplError

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.
