Create a new BufferOverrun error.

pub fn invalid_offset(offset: i64) -> Self

Create a new InvalidOffset error.

pub fn unsupported_type(type_name: impl Into<String>) -> Self

Create a new UnsupportedType error.

pub fn recursion_limit_exceeded(depth: u32) -> Self

Create a new RecursionLimitExceeded error.

pub fn string_length_exceeded(length: usize, max_length: usize) -> Self

Create a new StringLengthExceeded error.

pub fn invalid_string_encoding(offset: usize) -> Self

Trait Implementations

impl Debug for EvaluationError

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

Formats the value using the given formatter.

impl Display for EvaluationError

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

Formats the value using the given formatter.

impl Error for EvaluationError

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<EvaluationError> for LibmagicError

fn from(source: EvaluationError) -> Self

Converts to this type from the input type.

impl From<TypeReadError> for EvaluationError

fn from(source: TypeReadError) -> Self

Converts to this type from the input type.
