Enum HexParseError 

pub enum HexParseError {
    WrongLength {
        expected: usize,
        expected_hex_chars: usize,
        got: usize,
    },
    InvalidHex(FromHexError),
}

Errors from parsing a hex string into a fixed-size byte array.

Variants

WrongLength

The hex string (after stripping 0x) had the wrong length.

Fields

expected: usize

Required byte length.

expected_hex_chars: usize

Required hex-char length (expected * 2).

got: usize

Actual hex-char length observed.

InvalidHex(FromHexError)

The hex string contained a non-hex character.

Trait Implementations

impl Debug for HexParseError

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

Formats the value using the given formatter.

impl Display for HexParseError

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

Formats the value using the given formatter.

impl Error for HexParseError

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 HexParseError

fn from(source: FromHexError) -> Self

Converts to this type from the input type.
