Enum QuotedPrintableError

pub enum QuotedPrintableError {
    InvalidByte,
    LineTooLong,
    IncompleteHexOctet,
    InvalidHexOctet,
    LowercaseHexOctet,
}

An error type that represents different kinds of decoding errors.

Variants

InvalidByte

A byte was found in the input that was outside of the allowed range. The allowed range is the horizontal tab (ASCII 0x09), CR/LF characters (ASCII 0x0D and 0x0A), and anything in the ASCII range 0x20 to 0x7E, inclusive.

LineTooLong

Lines where found in the input that exceeded 76 bytes in length, excluding the terminating CRLF.

IncompleteHexOctet

An ‘=’ character was found in the input without the proper number of hex-characters following it. This includes ‘=’ characters followed by a single character and then the CRLF pair, for example.

InvalidHexOctet

An ‘=’ character was found with two following characters, but they were not hex characters. ‘=Hi’ for example would be an invalid encoding.

LowercaseHexOctet

An ‘=’ character was found with two following hex characters, but the hex characters were lowercase rather than uppercase. The spec explicitly requires uppercase hex to be used, so this is considered an error.

Trait Implementations

impl Clone for QuotedPrintableError

fn clone(&self) -> QuotedPrintableError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QuotedPrintableError

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

Formats the value using the given formatter.

impl Display for QuotedPrintableError

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

Formats the value using the given formatter.

impl Error for QuotedPrintableError

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 Hash for QuotedPrintableError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for QuotedPrintableError

fn cmp(&self, other: &QuotedPrintableError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for QuotedPrintableError

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

impl PartialOrd for QuotedPrintableError

fn partial_cmp(&self, other: &QuotedPrintableError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
