Struct obj_config_t 

#[repr(C)]
pub struct obj_config_t {
    pub sync_mode: obj_sync_mode_t,
    pub busy_timeout_ms: u64,
    pub skip_open_check: bool,
}

Flat C struct mirroring obj_engine::Config’s public knobs.

The struct is fixed-shape and freezes pre-1.0; the “size-field- at-front” extension trick is NOT in scope for v0. Future extensions require a new entry point with a new struct variant.

Field-by-field defaults mirror obj_engine::Config::default:

Field	Default
sync_mode	OBJ_SYNC_MODE_FULL
busy_timeout_ms	5000
skip_open_check	false (0)

Fields

sync_mode: obj_sync_mode_t

fsync primitive used after every WAL commit.

busy_timeout_ms: u64

Busy-lock timeout in milliseconds. 0 is treated as the engine’s default (5 s).

skip_open_check: bool

Skip the open-time integrity check. Non-zero = skip.
