Struct ReaderControl 

pub struct ReaderControl {
    pub requested: b32,
    pub received: b32,
    pub consumed: b32,
    pub lane: b2,
    pub head_valid: bool,
    pub read_pending: bool,
    pub dealt: b32,
    pub full: [bool; 8],
    pub error: bool,
}

Resettable control.

Every field here must start from a known value after reset, so it lives in a register with a reset value (all zero / false).

Fields

requested: b32

Beats requested (32 bits): sum of the burst lengths whose AR transfer has happened.

received: b32

Beats received (32 bits): R transfers written into the FIFO. Its low 6 bits are the FIFO write slot.

consumed: b32

Beats fully unpacked (32 bits). Its low 6 bits are the FIFO read slot.

lane: b2

Message within the current beat (0..=3, 2 bits): the beat’s 16-byte lane that will be dealt next.

head_valid: bool

The FIFO output register holds beat consumed, copied into head.

read_pending: bool

A FIFO read is outstanding: the RAM’s output will be valid next clock.

dealt: b32

Messages dealt (32 bits). Also the index of the next message, which picks its slice (dealt mod SLICES).

full: [bool; 8]

Slice buffers occupied (one bit per slice).

error: bool

Error seen (sticky): some R beat came back not OKAY.

Trait Implementations

impl Clone for ReaderControl

fn clone(&self) -> ReaderControl

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReaderControl

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

Formats the value using the given formatter.

impl Default for ReaderControl

fn default() -> ReaderControl

Returns the “default value” for a type.

impl Digital for ReaderControl

const BITS: usize

Associated constant that gives the total number of bits needed to represent the value.

fn static_kind() -> Kind

Returns the [Kind] (run time type descriptor) of the value as a static method

fn bin(self) -> Box<[BitX]>

Returns the binary representation of the value as a vector of [BitX].

fn dont_care() -> Self

Returns a “don’t care” value for the type.

fn bits() -> usize

Returns the number of bits needed to represent the value.

fn kind(&self) -> Kind

Returns the [Kind] (run time type descriptor) of the value.

fn typed_bits(self) -> TypedBits

Returns the value as a [TypedBits], which includes both the bits and the kind.

fn discriminant(self) -> TypedBits

Returns the discriminant of the value as a [TypedBits].

fn variant_kind(self) -> Kind

Returns the [Kind] of the variant if the value is an enum with variants.

fn binary_string(self) -> String

Returns the binary representation of the value as a string of ‘0’, ‘1’, and ‘X’.

impl PartialEq for ReaderControl

fn eq(&self, other: &ReaderControl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
