Errors that can occur when accessing a jeff program.

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.

StringOutOfBounds

String index into the module’s string table was out of bounds.

Fields

context: &'static str

The context in which the error occurred.

idx: u32

The requested index into the module’s strings.

count: usize

The total number of entries in the module’s strings.

StringNotUtf8

The encoded string had a non-utf8 name.

Fields

context: &'static str

The context in which the error occurred.

idx: u32

The index of the metadata name.

source: Utf8Error

The utf8 error

ValueOutOfBounds

Value index into the function’s value table was out of bounds.

Fields

idx: u32

The requested index into the function values.

count: usize

The total number of entries in the function values.

Trait Implementations

impl Debug for ReadError

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

Formats the value using the given formatter.

impl Display for ReadError

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

Formats the value using the given formatter.

impl Error for ReadError

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<(&'static str, u32, Utf8Error)> for ReadError

fn from(value: (&'static str, u32, Utf8Error)) -> Self

Converts to this type from the input type.

impl From<(&'static str, u32, usize)> for ReadError

fn from(value: (&'static str, u32, usize)) -> Self

Converts to this type from the input type.

impl From<(u32, usize)> for ReadError

fn from(value: (u32, usize)) -> Self

Converts to this type from the input type.

impl From<ReadError> for JeffError

fn from(value: ReadError) -> Self

Converts to this type from the input type.
