Enum DecodeError 

pub enum DecodeError {
    InvalidByte(u8),
    UnexpectedEnd,
    UnexpectedEscape(EscapedHex, char),
    LowercaseHex(EscapedHex),
    InvalidHex(EscapedHex),
}

An error trying to decode a tick-encoded string.

Variants

InvalidByte(u8)

Encountered an invalid byte in the string. This could either by a non-ASCII byte or an ASCII byte that requires escaping (see requires_escape).

UnexpectedEnd

Reached the end of the string following a backtick (`). A backtick must be followed by either another backtick or a 2-digit hex value.

UnexpectedEscape(EscapedHex, char)

Tried to decode a 2-digit hex value, but the value does not require escaping (see requires_escape).

LowercaseHex(EscapedHex)

Tried to decode a 2-digit hex value, but the hex value contained the values [a-f]. Escaped hex values must use [A-F].

InvalidHex(EscapedHex)

Tried to decode a 2-digit hex value, but an invalid hex digit was found. Escaped hex values must use the characters [0-9A-F].

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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>)
