Struct RuntimeResourceDriver 

pub struct RuntimeResourceDriver<R>
where
    R: DeviceRuntime,
{ /* private fields */ }

Production transaction adapter for a concrete DeviceRuntime.

Core owns reservation ordering, allocation authority, buffers, and capacity claims. This adapter therefore has no parallel allocator ledger: reserve, rollback, and release are acknowledgements, while commit consumes the exact core-issued allocation permit.

Implementations

impl<R> RuntimeResourceDriver<R>

where R: DeviceRuntime,

pub fn new(runtime: Arc<R>) -> Result<Self, VNextError>

pub fn runtime(&self) -> &Arc<R>

pub fn retained_pool_count(&self) -> usize

Number of pools retained after an indeterminate transaction outcome. Normal provisioning and shutdown leave this at zero.
