Errors that can be returned when trying to read from a buffer

Variants

TooManyBits

Too many bits requested to fit in the requested data type

Fields

requested: usize

The number of bits requested to read

max: usize

The number of bits that fit in the requested data type

NotEnoughData

Not enough data in the buffer to read all requested bits

Fields

requested: usize

The number of bits requested to read

bits_left: usize

the number of bits left in the buffer

IndexOutOfBounds

The requested position is outside the bounds of the stream or buffer

Fields

pos: usize

The requested position

size: usize

the number of bits in the buffer

UnmatchedDiscriminant

Unmatched discriminant found while trying to read an enum

Fields

discriminant: usize

The read discriminant

enum_name: String

The name of the enum that is trying to be read

Utf8Error(FromUtf8Error)

The read slice of bytes are not valid utf8

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ReadError

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

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 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<FromUtf8Error> for ReadError

fn from(err: FromUtf8Error) -> ReadError

Converts to this type from the input type.
