Implementations§

source§

impl Cfg

source

const _RESERVED_0: Pack32<u32, Self> = _

source

const CUR_TXRX_OVER_INT_DIS: Pack32<bool, Self> = _

Disable interrupts on completion.

source

const LAST: Pack32<bool, Self> = _

When set to 1, this bit indicates that the buffer this descriptor points to is the last data buffer.

source

const FIRST: Pack32<bool, Self> = _

When set to 1, this bit indicates that this descriptor contains the first buffer of data. It must be set to 1 in the first DES.

source

const CHAIN_MOD: Pack32<bool, Self> = _

When set to 1, this bit indicates that the second address in the descriptor is the next descriptor address. It must be set to 1.

source

const _RESERVED_1: Pack32<u32, Self> = _

Bits 29:5 are reserved.

source

const ERR: Pack32<bool, Self> = _

When some errors happen in transfer, this bit will be set to 1 by the IDMAC.

source

const DES_OWN: Pack32<bool, Self> = _

When set to 1, this bit indicates that the descriptor is owned by the IDMAC. When this bit is reset, it indicates that the descriptor is owned by the host. This bit is cleared when the transfer is over.

source

const FIELDS: &'static [(&'static str, Pack32<u32, Self>)] = _

source

const fn from_bits(bits: u32) -> Self

Constructs a new instance of Self from the provided raw bits.

source

const fn new() -> Self

Constructs a new instance of Self with all bits set to 0.

source

const fn bits(self) -> u32

Returns the raw bit representatiion of self as an integer.

source

fn with<T>(self, field: Pack32<T, Self>, value: T) -> Self
where T: FromBits<u32>,

Packs the bit representation of value into self at the bit range designated by field, returning a new bitfield.

source

fn set<T>(&mut self, field: Pack32<T, Self>, value: T) -> &mut Self
where T: FromBits<u32>,

Packs the bit representation of value into self at the range designated by field, mutating self in place.

source

fn get<T>(self, field: Pack32<T, Self>) -> T
where T: FromBits<u32>,

Unpacks the bit range represented by field from self, and converts it into a T-typed value.

§Panics

This method panics if self does not contain a valid bit pattern for a T-typed value, as determined by T’s FromBits::try_from_bits implementation.

source

fn try_get<T>(self, field: Pack32<T, Self>) -> Result<T, T::Error>
where T: FromBits<u32>,

Unpacks the bit range represented by field from self and attempts to convert it into a T-typed value.

§Returns
  • Ok(T) if a T-typed value could be constructed from the bits in src
  • Err(T::Error) if src does not contain a valid bit pattern for a T-typed value, as determined by T’s [FromBits::try_from_bits implementation.
source

fn assert_valid()

Asserts that all the packing specs for this type are valid.

This is intended to be used in unit tests.

source

fn display_ascii(&self) -> impl Display

Returns a value that formats this bitfield in a multi-line format, using only ASCII characters.

This is equivalent to formatting this bitfield using a {} display specifier, but will never use Unicode box-drawing characters, even when an upstream formatter uses the {:#} fmt::Display specifier. This is intended for use on platforms where Unicode box drawing characters are never available.

source

fn display_unicode(&self) -> impl Display

Returns a value that formats this bitfield in a multi-line format, always using Unicode box-drawing characters.

This is equivalent to formatting this bitfield using a {:#} format specifier, but will always use Unicode box-drawing characters, even when an upstream formatter uses the {} fmt::Display specifier.

source

fn fmt_ascii(&self, f: &mut Formatter<'_>) -> Result

source

fn fmt_unicode(&self, f: &mut Formatter<'_>) -> Result
