Trait ConfigAccess

pub trait ConfigAccess {
    // Required methods
    fn get_register(&self, selector: ConfigSelector, register: u16) -> u32;
    fn set_register(&self, selector: ConfigSelector, register: u16, value: u32);

    // Provided methods
    fn get_fixed_register<T: FixedConfigRegister>(
        &self,
        selector: ConfigSelector,
    ) -> T { ... }
    fn set_fixed_register<T: FixedConfigRegister>(
        &self,
        selector: ConfigSelector,
        value: T,
    ) { ... }
}

Provides methods to access PCI configuration space.

Implementations may only offer access to a limited number of registers on a specific range of segments/busses.

Required Methods

fn get_register(&self, selector: ConfigSelector, register: u16) -> u32

Get a specific 32-bit register in PCI configuration space.

fn set_register(&self, selector: ConfigSelector, register: u16, value: u32)

Set a specific 32-bit register in PCI configuration space.

Provided Methods

fn get_fixed_register<T: FixedConfigRegister>( &self, selector: ConfigSelector, ) -> T

Get a register in PCI configuration space with an offset defined by the output type.

fn set_fixed_register<T: FixedConfigRegister>( &self, selector: ConfigSelector, value: T, )

Set a register in PCI configuration space with an offset defined by the input type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
