Enum bson::ser::Error

#[non_exhaustive]
pub enum Error {
    Io(Arc<Error>),
    InvalidDocumentKey(Bson),
    SerializationError {
        message: String,
    },
    UnsupportedUnsignedInteger(u64),
}

Possible errors that can arise during encoding.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Arc<Error>)

A std::io::Error encountered while serializing.

InvalidDocumentKey(Bson)

A key could not be serialized to a BSON string.

SerializationError

A general error that occurred during serialization. See: https://docs.rs/serde/1.0.110/serde/ser/trait.Error.html#tymethod.custom

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

Fields of SerializationError

message: String

A message describing the error.

UnsupportedUnsignedInteger(u64)

Returned when serialization of an unsigned integer was attempted. BSON only supports 32-bit and 64-bit signed integers.

To serialize unsigned integers to BSON, use an appropriate helper from crate::serde_helpers or enable the “u2i” feature flag.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

impl Error for Error

fn custom<T: Display>(msg: T) -> Error

Used when a Serialize implementation encounters any error while serializing a type.

impl From<Error> for Error

fn from(err: Error) -> Error

Performs the conversion.
