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

Formats the value using the given formatter.

impl Display for FromHexError

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

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 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
