Implementations

impl DummyDstTag

pub const fn header(&self) -> &DummyTestHeader

pub const fn payload(&self) -> &[u8]

Trait Implementations

impl Debug for DummyDstTag

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

Formats the value using the given formatter.

impl MaybeDynSized for DummyDstTag

const BASE_SIZE: usize = 8usize

The true base size of the struct without any implicit or additional padding. Note that size_of::<T>() isn’t sufficient, as for example the type could have three u32 fields, which would add an implicit u32 padding. However, this constant must always fulfill BASE_SIZE >= size_of::<Self::Header>().

type Header = DummyTestHeader

The associated Header of this tag.

fn dst_len(header: &Self::Header) -> Self::Metadata

Returns the amount of items in the dynamically sized portion of the DST. Note that this is not the amount of bytes. So if the dynamically sized portion is 16 bytes in size and each element is 4 bytes big, then this function must return 4.

fn header(&self) -> &Self::Header

Returns the corresponding Header.

fn payload(&self) -> &[u8]

Returns the payload, i.e., all memory that is not occupied by the Header of the type.

fn as_bytes(&self) -> BytesRef<'_, Self::Header>

Returns the whole allocated bytes for this structure encapsulated in BytesRef. This includes padding bytes. To only get the “true” tag data, read the tag size from Self::header and create a sub slice.

fn as_ptr(&self) -> *const Self::Header

Returns a pointer to this structure.

impl PartialEq for DummyDstTag

fn eq(&self, other: &DummyDstTag) -> 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.

impl Pointee for DummyDstTag

where [u8]: Pointee,

type Metadata = <[u8] as Pointee>::Metadata

The metadata type for pointers and references to this type.

impl Tag for DummyDstTag

const ID: Self::IDType = {transmute(0x0000002a): <test_utils::DummyDstTag as tag::Tag>::IDType}

The ID of this tag. This should be unique across all implementors.

type IDType = u32

The ID type that identifies the tag.

impl Eq for DummyDstTag
