Enum bson::UuidRepresentation
source · pub enum UuidRepresentation {
Standard,

}
Expand description
Enum of the possible representations to use when converting between Uuid
and Binary
.
This enum is necessary because the different drivers used to have different ways of encoding
UUIDs, with the BSON subtype: 0x03 (UUID old).
If a UUID has been serialized with a particular representation, it MUST
be deserialized with the same representation.
Example:
use bson::{Binary, uuid::{Uuid, UuidRepresentation}};
let uuid = Uuid::parse_str("00112233445566778899AABBCCDDEEFF")?;
let bin = Binary::from_uuid_with_representation(uuid, UuidRepresentation::PythonLegacy);
// This conversion fails, since the binary holds a PythonLegacy UUID, so we're required to specify
// that.
assert!(bin.to_uuid().is_err());
// This conversion succeeds, since we specified the correct representation.
let new_uuid = bin.to_uuid_with_representation(UuidRepresentation::PythonLegacy)?;
assert_eq!(new_uuid, uuid);
Variants§
Standard
The canonical representation of UUIDs in BSON (binary with subtype 0x04)
CSharpLegacy
The legacy representation of UUIDs in BSON used by the C# driver (binary subtype 0x03)
JavaLegacy
The legacy representation of UUIDs in BSON used by the Java driver (binary subtype 0x03)
PythonLegacy
The legacy representation of UUIDs in BSON used by the Python driver, which is the same format as STANDARD, but has binary subtype 0x03
