Struct ObjectId

Source

pub struct ObjectId(/* private fields */);

Available on crate feature postgres only.

Expand description

A unique identifier for an object within a pool.

ObjectId is an opaque wrapper around a numeric identifier. IDs are guaranteed to be unique and monotonically increasing within a single pool. Each new object receives an identifier greater than the previously created object, but IDs are not guaranteed to be consecutive (gaps may exist).

This type is intended to be used as an opaque handle for identifying objects. It implements common traits such as Copy, Clone, Eq, Ord, and Hash so that it can be compared, ordered, or stored in sets and maps. It should not be used for arithmetic or treated as a raw number.
