Enum bson::uuid::Error

#[non_exhaustive]
pub enum Error {
    InvalidUuidString {
        message: String,
    },
    RepresentationMismatch {
        expected_binary_subtype: BinarySubtype,
        actual_binary_subtype: BinarySubtype,

}

Errors that can occur during Uuid construction and generation.

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.

InvalidUuidString

Fields

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.

message: String

Error returned when an invalid string is provided to Uuid::parse_str.

RepresentationMismatch

Fields

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.

expected_binary_subtype: BinarySubtype

The subtype that was expected given the requested representation.

actual_binary_subtype: BinarySubtype

The actual subtype of the binary value.

requested_representation: UuidRepresentation

The requested representation.

Error returned when the representation specified does not match the underlying crate::Binary value in crate::Binary::to_uuid_with_representation.

InvalidLength

Fields

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.

length: usize

The actual length of the data.

Error returned from crate::Binary::to_uuid if the underling data is not 16 bytes long.

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 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()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
