Enum EncodingError 

pub enum EncodingError {
    BufferTooShort,
    Malformed {
        read: usize,
        write: usize,
        length: usize,
        offset: usize,
    },
    Unmappable {
        read: usize,
        write: usize,
        c: char,
    },
    Other {
        msg: Cow<'static, str>,
    },
}

Variants

BufferTooShort

The length of the output buffer is too short.
If this error is returned, it is guaranteed that the encoder/decoder is consuming the input buffer.

Malformed

Malformed byte sequence is found.

The input and output buffer have consumed read and write bytes respectively.
Malformed sequence occurs input[read-length-offset..read-offset].

Only the decoder returns this error.

Fields

read: usize

write: usize

length: usize

offset: usize

Unmappable

A UTF-8 character c cannot map any codepoints of the target encoding.

The input and output buffer have consumed read and write bytes respectively.
read includes the length of c. Thus, the correctly read length is read - c.len_utf8().
write does not include the length of c because encoder cannot write unmapped characters.

Only the encoder returns this error.

Fields

read: usize

write: usize

c: char

Other

Other errors.

Fields

msg: Cow<'static, str>

Implementations

impl EncodingError

pub fn buffer_too_short(&self) -> bool

Trait Implementations

impl Clone for EncodingError

fn clone(&self) -> EncodingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncodingError

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

Formats the value using the given formatter.

impl Display for EncodingError

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

Formats the value using the given formatter.

impl Error for EncodingError

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.
