Struct PartitionDescriptor 

pub struct PartitionDescriptor {
    pub pointer: String,
    pub interval: PartitionInterval,
    pub premake: u32,
    pub retention: Option<u32>,
}

Declarative range partitioning for one type, maintained by pg_partman.

A type carries at most one of these: a table has exactly one partition key, so a second declaration isn’t a refinement, it’s a contradiction. See validate_partitions.

Fields

pointer: String

The property partitioned on. Must be a non-nullable date/timestamp property of this type — PostgreSQL requires the partition key to be part of the primary key and to never be NULL.

interval: PartitionInterval

premake: u32

How many future partitions to keep pre-created. A write landing in a range that doesn’t exist yet fails, so this is the safety margin against maintenance falling behind.

retention: Option<u32>

Drop partitions older than this many intervals. None keeps everything — the safe default, since the alternative silently deletes data on a schedule.
