Struct BaseCap

pub struct BaseCap<'a> { /* private fields */ }

A single capability within a specific device’s configuration space.

This is a generic representation of a capability. It provides only low-level methods for reading and writing the capability fields. Other structs in this module will wrap this struct and provide higher level methods for accessing specific fields.

The 'a lifetime references the Device this capability belongs to.

Implementations

impl BaseCap<'_>

pub fn id(&self) -> u8

Returns the ID of this capability.

pub fn next(&self) -> u8

Returns the next capability pointer.

pub fn read8(&self, offset: u16) -> u8

Reads an 8-bit value relative to the base of this capability.

pub fn write8(&self, offset: u16, val: u8)

Writes an 8-bit value relative to the base of this capability.

pub fn read16(&self, offset: u16) -> u16

Reads a 16-bit value relative to the base of this capability.

pub fn write16(&self, offset: u16, val: u16)

Writes a 16-bit value relative to the base of this capability.

pub fn read32(&self, offset: u16) -> u32

Reads a 32-bit value relative to the base of this capability.

pub fn write32(&self, offset: u16, val: u32)

Writes a 32-bit value relative to the base of this capability.
