Tuple Fields

0: u32

Implementations

impl Cfg

const _RESERVED_0: Pack32<u32, Self> = _

const CUR_TXRX_OVER_INT_DIS: Pack32<bool, Self> = _

Disable interrupts on completion.

const LAST: Pack32<bool, Self> = _

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

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.

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.

const _RESERVED_1: Pack32<u32, Self> = _

Bits 29:5 are reserved.

const ERR: Pack32<bool, Self> = _

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

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.

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

const fn from_bits(bits: u32) -> Self

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

const fn new() -> Self

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

const fn bits(self) -> u32

Returns the raw bit representatiion of self as an integer.

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.

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.

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.

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.

fn assert_valid()

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

This is intended to be used in unit tests.

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.

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.

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

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