[−][src]Struct pci_types::EndpointHeader

pub struct EndpointHeader(_);

Endpoints have a Type-0 header, so the remainder of the header is of the form:

Implementations

impl EndpointHeader[src]

pub fn from_header(
    header: PciHeader,
    access: &impl ConfigRegionAccess
) -> Option<EndpointHeader>[src]

pub fn header(&self) -> PciHeader[src]

pub fn bar(&self, slot: u8, access: &impl ConfigRegionAccess) -> Option<Bar>[src]

Get the contents of a BAR in a given slot. Empty bars will return None.

Note

64-bit memory BARs use two slots, so if one is decoded in e.g. slot #0, this method should not be called for slot #1
