Expand description
Errors that can be encountered by decoding a type
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
UnexpectedEnd
Fields
additional: usize
Gives an estimate of how many extra bytes are needed.
Note: this is only an estimate and not indicative of the actual bytes needed.
Note: Bincode has no look-ahead mechanism. This means that this will only return the amount of bytes to be read for the current action, and not take into account the entire data structure being read.
The reader reached its end but more bytes were expected.
LimitExceeded
The given configuration limit was exceeded
InvalidIntegerType
Fields
expected: IntegerType
The type that was being read from the reader
found: IntegerType
The type that was encoded in the data
Invalid type was found. The decoder tried to read type expected
, but found type found
instead.
NonZeroTypeIsZero
Fields
non_zero_type: IntegerType
The type that was being read from the reader
The decoder tried to decode any of the NonZero*
types but the value is zero
UnexpectedVariant
Fields
type_name: &'static str
The type name that was being decoded.
allowed: &'static AllowedEnumVariants
The variants that are allowed
found: u32
The index of the enum that the decoder encountered
Invalid enum variant was found. The decoder tried to decode variant index found
, but the variant index should be between min
and max
.
Utf8
Fields
inner: Utf8Error
The inner error
The decoder tried to decode a str
, but an utf8 error was encountered.
InvalidCharEncoding([u8; 4])
The decoder tried to decode a char
and failed. The given buffer contains the bytes that are read at the moment of failure.
InvalidBooleanValue(u8)
The decoder tried to decode a bool
and failed. The given value is what is actually read.
ArrayLengthMismatch
Fields
required: usize
The length of the array required by the rust type.
found: usize
The length of the array found in the binary format.
The decoder tried to decode an array of length required
, but the binary data contained an array of length found
.
OutsideUsizeRange(u64)
The encoded value is outside of the range of the target usize type.
This can happen if an usize was encoded on an architecture with a larger usize type and then decoded on an architecture with a smaller one. For example going from a 64 bit architecture to a 32 or 16 bit one may cause this error.
EmptyEnum
Fields
type_name: &'static str
The type that was being decoded
Tried to decode an enum with no variants
InvalidDuration
Fields
secs: u64
The number of seconds in the duration.
nanos: u32
The number of nanoseconds in the duration, which when converted to seconds and added to
secs
, overflows a u64
.
The decoder tried to decode a Duration and overflowed the number of seconds.
InvalidSystemTime
Fields
duration: Duration
The duration which could not have been added to
UNIX_EPOCH
The decoder tried to decode a SystemTime and overflowed
CStringNulError
Fields
position: usize
Nul byte position
The decoder tried to decode a CString
, but the incoming data contained a 0 byte
Io
Fields
inner: Error
The IO error expected
additional: usize
Gives an estimate of how many extra bytes are needed.
Note: this is only an estimate and not indicative of the actual bytes needed.
Note: Bincode has no look-ahead mechanism. This means that this will only return the amount of bytes to be read for the current action, and not take into account the entire data structure being read.
The reader encountered an IO error but more bytes were expected.
OtherString(String)
An uncommon error occurred, see the inner text for more information
Serde(DecodeError)
A serde-specific error that occurred while decoding.
