Struct Config 

pub struct Config {

    pub origin: Origin,
    pub rotation_policy: RotationPolicy,
    pub retention_policy: RetentionPolicy,
    pub compression: Compression,
    pub compression_threshold: usize,
    pub compact: bool,
    pub open_mode: LogOpenMode,

}

Configuration for a journal log.

Fields

origin: Origin

rotation_policy: RotationPolicy

Policy for when to rotate active files

retention_policy: RetentionPolicy

Policy for when to remove old files

compression: Compression

DATA object compression algorithm.

compression_threshold: usize

Minimum uncompressed DATA payload size before compression is attempted.

compact: bool

Use the systemd compact journal on-disk layout.

open_mode: LogOpenMode

Active-file creation mode.

identity_mode: LogIdentityMode

Missing identity handling mode.

boot_id: Option<Uuid>

Optional boot ID override for new files and strict identity mode.

strict_systemd_naming: bool

Use systemd’s <source>.journal active filename policy.

The default is false so active files use the chain filename form <source>@<seqnum_id>-<head_seqnum>-<head_realtime>.journal.

live_publish_every_entries: u64

Explicit live-reader publication cadence.

1 is the default systemd-compatible behavior, 0 disables explicit per-entry live publication, and values greater than 1 publish after every N entries.

field_name_policy: FieldNamePolicy

Field-name policy for caller-provided fields.

file_mode: u32

Permission bits for newly created journal files on Unix platforms.

The default follows systemd journald’s 0640 journal-file mode.
