pub struct EndTag { /* private fields */ }
Expand description

The end tag ends the information struct.

Trait Implementations§

Source§

impl Debug for EndTag

Source§

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

Formats the value using the given formatter. Read more
Source§

impl Default for EndTag

Source§

fn default() -> Self

Returns the “default value” for a type. Read more
Source§

impl MaybeDynSized for EndTag

Source§

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>(). Read more
Source§

type Header = TagHeader

The associated Header of this tag.
Source§

fn dst_len(_: &TagHeader)

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. Read more
Source§

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

Returns the corresponding Header.
Source§

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

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

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.
Source§

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

Returns a pointer to this structure.
Source§

impl Tag for EndTag

Source§

const ID: TagType = TagType::End

The ID of this tag. This should be unique across all implementors. Read more
Source§

type IDType = TagType

The ID type that identifies the tag.
