Struct StorageSection 

pub struct StorageSection {
    pub default_namespace: Option<String>,
    pub archive_on_gc: Option<bool>,
    pub archive_max_days: Option<i64>,
    pub max_memory_mb: Option<usize>,
    pub db_mmap_size_bytes: Option<i64>,
}

v0.7.x (#1146) — [storage] sectioned storage configuration.

Wire format:

[storage]
default_namespace = "alphaone"
archive_on_gc     = true
archive_max_days  = 90
max_memory_mb     = 4096

Carries the previously-flat top-level fields default_namespace, archive_on_gc, archive_max_days, max_memory_mb. The db path stays top-level per the #1146 I4 carve-out (path expansion semantics pinned by #507).

Fields

default_namespace: Option<String>

Default namespace for new memories when the caller’s request omits one. Folded from the previously-flat top-level default_namespace field.

archive_on_gc: Option<bool>

Whether to archive memories before GC deletion. Folded from archive_on_gc. Default true.

archive_max_days: Option<i64>

Archive retention ceiling in days. None (default) disables the automatic purge. Folded from archive_max_days.

max_memory_mb: Option<usize>

Memory budget in MB for the auto tier selector. Folded from max_memory_mb.

db_mmap_size_bytes: Option<i64>

#1579 B7 — sqlite PRAGMA mmap_size in bytes. 0 disables memory-mapped I/O (stock SQLite semantics); negative values are treated as unset and fall through the ladder. Env override: AI_MEMORY_DB_MMAP_SIZE (see ENV_DB_MMAP_SIZE). Compiled default: 256 MiB (crate::storage::DEFAULT_DB_MMAP_SIZE_BYTES) — the only across-the-board winner of the P1 perf-audit PRAGMA A/B (15-30% on large-corpus reads).

Trait Implementations

impl Clone for StorageSection

fn clone(&self) -> StorageSection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageSection

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

Formats the value using the given formatter.

impl Default for StorageSection

fn default() -> StorageSection

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StorageSection

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for StorageSection

impl PartialEq for StorageSection

fn eq(&self, other: &StorageSection) -> 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.

impl Serialize for StorageSection

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
