Struct pci_driver::regions::PciRegionSnapshot

pub struct PciRegionSnapshot { /* private fields */ }

Use this to take snapshots of anything that is an AsPciSubregion.

Implementations

impl PciRegionSnapshot

pub fn take<'a>(
    as_subregion: impl AsPciSubregion<'a>
) -> Result<PciRegionSnapshot>
