open suspend fun findOne(options: FindOptions<Document>.() -> Unit = {}, filter: FilterQuery<Document>.() -> Unit): Document?

Finds a document in this collection that satisfies filter.

If multiple predicates are specified, and and operator is implied.

This function doesn't check that there is exactly one value in the collection. It simply returns the first matching document it finds.

Example

class User(
    val name: String,
    val age: Int,
)

collection.findOne {
    User::name eq "foo"
    User::age eq 10
}
