Enum Temperature 

#[repr(i32)]
pub enum Temperature {
    Unknown = 0,
    Hot = 4,
    Warm = 8,
    Cool = 10,
    Cold = 12,
    Ice = 16,
}

Storage tier hint for a file, passed through to the FileSystem so it can place or encode the file differently.

Mirrors rocksdb::Temperature from include/rocksdb/types.h, including its discriminants, so Temperature::Warm as i32 is a valid argument to the *_temperature setters on Options. Values RocksDB adds in future versions decode as Temperature::Unknown, as does the kLastTemperature sentinel, which is not a real tier.

Upstream leaves gaps between the discriminants so new tiers can be slotted in. This feature is experimental upstream and subject to change.

Variants

Unknown = 0

No tier recorded. Also the decoding of any unrecognised value.

Hot = 4

Frequently read.

Warm = 8

Read now and then.

Cool = 10

Rarely read.

Cold = 12

Read very rarely.

Ice = 16

Archival; expect slow reads.
