Enum HexError 

pub enum HexError {
    InvalidHex,
    InvalidLength {
        expected: usize,
        got: usize,
    },
}

Errors produced when decoding hexadecimal strings.

Requires feature encoding-hex.

In debug builds InvalidLength carries expected/got fields for development debugging. In release builds this variant is opaque to prevent leaking expected-length metadata.

Variants

InvalidHex

The string is not valid hexadecimal.

InvalidLength

Length mismatch in debug builds (detailed).

Fields

expected: usize

Number of bytes the target type requires.

got: usize

Number of bytes actually decoded.

Trait Implementations

impl Clone for HexError

fn clone(&self) -> HexError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HexError

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

Formats the value using the given formatter.

impl Display for HexError

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

Formats the value using the given formatter.

impl Error for HexError

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 HexError

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