Parse number error.

Variants

TooShortToStartWithPrefix

Too short to start with a prefix such as 0x or 0.

Fields of TooShortToStartWithPrefix

prefix: &'static [u8]

The prefix, eg 0x.

minimum_size_without_prefix: usize

Minimum size without prefix.

DoesNotStartWithPrefix

Does not start with a prefix such as 0x or 0.

Fields of DoesNotStartWithPrefix

prefix: &'static [u8]

The prefix, eg 0x.

HexadecimalFixedWidthNumberHasWrongNumberOfBytes

A fixed width hexadecimal number has the wrong number of bytes.

Fields of HexadecimalFixedWidthNumberHasWrongNumberOfBytes

fixed_width: usize

Fixed width.

OctalFixedWidthNumberHasWrongNumberOfBytes

A fixed width octal number has the wrong number of bytes.

Fields of OctalFixedWidthNumberHasWrongNumberOfBytes

fixed_width: usize

Fixed width.

TooShort

A number must be at least one byte long.

TooShortWithMinusSign

A number must be at least two bytes long if it has a minus sign.

ScalingOverflow

Overflow when scaling.

AddOverflow

Overflow when adding.

InvalidByte

An invalid byte.

Fields of InvalidByte

byte: u8

Value of invalid byte.

WasZero

Non-zero numbers are not allowed to be zero.

WasMaximum

eg 0xFFFF or 0xFFFFFFFF; for example, PCI vendor and device numbers are not allowed to be 0xFFFF.

TooSmall

Too small.

TooLarge

Too large.

OutOfRange

Out of range without being zero, maximum, too small or too large.

Trait Implementations

impl Clone for ParseNumberError

fn clone(&self) -> ParseNumberError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNumberError

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

Formats the value using the given formatter.

impl Display for ParseNumberError

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

Formats the value using the given formatter.

impl Error for ParseNumberError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
