Enum ReadError 

pub enum ReadError {
    InvalidTag(u8),
    MissingNullTerminator,
    InvalidUtf8,
    InvalidBoolValue,
    InvalidFloatLength,
    InvalidFdLength,
    TimestampOutOfRange,
    InvalidSubfield,
    InvalidKeyValuePair,
    InvalidFdNumber(u32),
}

An error while reading argdata.

Variants

InvalidTag(u8)

The data contained the given tag, which doesn’t correspond to any known type.

MissingNullTerminator

The data represents a string, but it wasn’t null-terminated.

InvalidUtf8

The data represents a string, but it contained invalid UTF-8.

InvalidBoolValue

The data represents a boolean, but it contained a value other than ‘false’ or ‘true’.

InvalidFloatLength

The data represents a float, but wasn’t exactly 64 bits.

InvalidFdLength

The data represents a file descriptor, but wasn’t exactly 32 bits.

TimestampOutOfRange

The data represents a timestamp that does not fit in a Timespec.

InvalidSubfield

The data contains a subfield (of a map or seq) with an incomplete or too large length.

InvalidKeyValuePair

The data contains a map with an incomplete key-value pair.

InvalidFdNumber(u32)

The data represents a file descriptor that doesn’t exist. (Possibly because there were no file descriptors ‘attached’ to the argdata value at all.)

Trait Implementations

impl Clone for ReadError

fn clone(&self) -> ReadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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<ReadError> for NotRead

fn from(e: ReadError) -> NotRead

Converts to this type from the input type.

impl From<Utf8Error> for ReadError

fn from(_: Utf8Error) -> ReadError

Converts to this type from the input type.

impl PartialEq for ReadError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
