Trait Implementations

impl Clone for SuperSegmentHeader

fn clone(&self) -> SuperSegmentHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SuperSegmentHeader

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

Formats the value using the given formatter.

impl Decode for SuperSegmentHeader

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<'de> Deserialize<'de> for SuperSegmentHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for SuperSegmentHeader

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl MaxEncodedLen for SuperSegmentHeader

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq for SuperSegmentHeader

fn eq(&self, other: &SuperSegmentHeader) -> 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 Serialize for SuperSegmentHeader

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TrivialType for SuperSegmentHeader

where Unaligned<SuperSegmentIndex>: TrivialType, SuperSegmentRoot: TrivialType, Blake3Hash: TrivialType, Unaligned<SegmentIndex>: TrivialType, Unaligned<BlockNumber>: TrivialType, u32: TrivialType,

const METADATA: &[u8]

Data structure metadata in binary form, describing shape and types of the contents, see [IoTypeMetadataKind] for encoding details.

const SIZE: u32 = _

unsafe fn read_unaligned(bytes: &[u8]) -> Option<Self>

unsafe fn from_bytes(bytes: &[u8]) -> Option<&Self>

Create a reference to a type, which is represented by provided memory.

unsafe fn from_bytes_unchecked(bytes: &[u8]) -> &Self

fn as_bytes(&self) -> &[u8; { _ }]

Access the underlying byte representation of a data structure

unsafe fn as_bytes_mut(&mut self) -> &mut [u8; { _ }]

Access the underlying mutable byte representation of a data structure.
