Enum WriteError 

pub enum WriteError {
    Io(Error),
    NaNOrInfinity,
    EmptyDocument,
    MultipleRootValues,
    Poisoned,
    InvalidOption(&'static str),
    FrameMismatch,
    KeyOutsideObject,
    ExtensionWithoutPayload,
}

Errors returned by the writer.

After any error mid-document the writer is poisoned: subsequent calls fail with WriteError::Poisoned instead of producing a malformed document.

Variants

Io(Error)

The underlying Sink returned an io::Error.

NaNOrInfinity

f64 was NaN or ±∞.

EmptyDocument

Writer::finish was called with no root value.

MultipleRootValues

More than one root value was pushed.

Poisoned

A previous error left the writer in an unrecoverable state.

InvalidOption(&'static str)

WriterOptions failed validation.

FrameMismatch

RawWriter::end_array / end_object was called with a mismatched or absent top frame.

KeyOutsideObject

RawWriter::push_key was called outside an object frame.

ExtensionWithoutPayload

An extension header was written but no payload value followed before the enclosing frame closed (or finish/snapshot_trailer was called).

Trait Implementations

impl Debug for WriteError

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

Formats the value using the given formatter.

impl Display for WriteError

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

Formats the value using the given formatter.

impl Error for WriteError

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<Error> for WriteError

fn from(e: Error) -> Self

Converts to this type from the input type.
