Struct DerivedStateReplayConfig 

pub struct DerivedStateReplayConfig {
    pub backend: DerivedStateReplayBackend,
    pub replay_dir: PathBuf,
    pub durability: DerivedStateReplayDurability,
    pub max_envelopes: usize,
    pub max_sessions: usize,
}

Typed replay retention configuration for derived-state consumers.

Fields

backend: DerivedStateReplayBackend

Replay backend used to retain envelopes.

replay_dir: PathBuf

Filesystem directory used by the disk backend.

durability: DerivedStateReplayDurability

Durability policy used by the disk backend.

max_envelopes: usize

Maximum number of retained envelopes per session.

max_sessions: usize

Maximum number of retained sessions visible to the disk backend.

Implementations

impl DerivedStateReplayConfig

pub fn checkpoint_only() -> Self

Returns a checkpoint-only replay configuration with no retained runtime tail.

This is the lowest-memory derived-state mode. Consumers rely on their own durable checkpoints and accept that retained envelope replay is unavailable.

pub const fn is_enabled(&self) -> bool

Returns whether the runtime-owned replay tail is enabled.

Trait Implementations

impl Clone for DerivedStateReplayConfig

fn clone(&self) -> DerivedStateReplayConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DerivedStateReplayConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DerivedStateReplayConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DerivedStateReplayConfig

fn eq(&self, other: &DerivedStateReplayConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
