Enum FormatError 

pub enum FormatError {
    MalformedDocument {
        format: &'static str,
        detail: String,
    },
    PayloadTooLarge,
    Read {
        detail: String,
    },
    Encoding {
        format: &'static str,
        detail: String,
    },
}

A failure while decoding or encoding a Serde document.

Variants

MalformedDocument

The input is not a valid document in the named format.

Fields

format: &'static str

The format’s display name.

detail: String

Decoder detail (position information where the decoder provides it).

PayloadTooLarge

The input stream ended the transfer because a configured size limit was exceeded (see crate::PayloadLimitExceeded).

Read

The underlying reader failed before the document ended.

Fields

detail: String

Human-readable I/O detail.

Encoding

The value failed to encode in the named format.

Fields

format: &'static str

The format’s display name.

detail: String

Encoder detail.

Implementations

impl FormatError

pub fn from_read_error(error: &Error) -> Self

Classify a decoder-side I/O failure: the payload-limit sentinel becomes FormatError::PayloadTooLarge; everything else is a read failure.

Trait Implementations

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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>)
