Enum FromHexError

pub enum FromHexError {
    InvalidHexCharacter {
        c: char,
        index: usize,
    },
    OddLength,
    InvalidStringLength,
}

The error type for decoding a hex string into Vec<u8> or [u8; N].

Variants

InvalidHexCharacter

An invalid character was found. Valid ones are: 0...9, a...f or A...F.

Fields

c: char

index: usize

OddLength

A hex string’s length needs to be even, as two digits correspond to one byte.

InvalidStringLength

If the hex string is decoded into a fixed sized container, such as an array, the hex string’s length * 2 has to match the container’s length.

Trait Implementations

impl Clone for FromHexError

fn clone(&self) -> FromHexError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FromHexError

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

Formats the value using the given formatter.

impl Display for FromHexError

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

Formats the value using the given formatter.

impl Error for FromHexError

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<FromHexError> for AddressError

fn from(source: FromHexError) -> AddressError

Converts to this type from the input type.

impl From<FromHexError> for BytesErrors

fn from(source: FromHexError) -> BytesErrors

Converts to this type from the input type.

impl From<FromHexError> for SignedError

fn from(source: FromHexError) -> SignedError

Converts to this type from the input type.

impl From<FromHexError> for UintError

fn from(source: FromHexError) -> UintError

Converts to this type from the input type.

impl PartialEq for FromHexError

fn eq(&self, other: &FromHexError) -> 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.
