Struct kernel::utilities::registers::ReadWrite

pub struct ReadWrite<T, R = ()>
where
    T: UIntLike,
    R: RegisterLongName,
{ /* private fields */ }

Read/Write registers.

For accessing and manipulating the register contents, the Readable, Writeable and ReadWriteable traits are implemented.

Trait Implementations

impl<T, R> Readable for ReadWrite<T, R>

where T: UIntLike, R: RegisterLongName,

type T = T

type R = R

fn get(&self) -> <ReadWrite<T, R> as Readable>::T

Get the raw register value

fn read(&self, field: Field<Self::T, Self::R>) -> Self::T

Read the value of the given field

fn read_as_enum<E>(&self, field: Field<Self::T, Self::R>) -> Option<E>

where E: TryFromValue<Self::T, EnumType = E>,

Set the raw register value

fn extract(&self) -> LocalRegisterCopy<Self::T, Self::R>

Make a local copy of the register

fn is_set(&self, field: Field<Self::T, Self::R>) -> bool

Check if one or more bits in a field are set

fn any_matching_bits_set(&self, field: FieldValue<Self::T, Self::R>) -> bool

Check if any bits corresponding to the mask in the passed FieldValue are set. This function is identical to is_set() but operates on a FieldValue rather than a Field, allowing for checking if any bits are set across multiple, non-contiguous portions of a bitfield.

fn matches_all(&self, field: FieldValue<Self::T, Self::R>) -> bool

Check if all specified parts of a field match

fn matches_any(&self, fields: &[FieldValue<Self::T, Self::R>]) -> bool

Check if any of the passed parts of a field exactly match the contained value. This allows for matching on unset bits, or matching on specific values in multi-bit fields.

impl<T, R> Writeable for ReadWrite<T, R>

where T: UIntLike, R: RegisterLongName,

type T = T

type R = R

fn set(&self, value: T)

Set the raw register value

fn write(&self, field: FieldValue<Self::T, Self::R>)

Write the value of one or more fields, overwriting the other fields with zero

fn modify_no_read( &self, original: LocalRegisterCopy<Self::T, Self::R>, field: FieldValue<Self::T, Self::R>, )

Write the value of one or more fields, maintaining the value of unchanged fields via a provided original value, rather than a register read.
