Struct VecU64 

pub struct VecU64(/* private fields */);

A u64 encoded with the same framing as a Vec<u8> of its big-endian bytes.

The encoding is a varint length of 8 followed by the 8 big-endian bytes, byte-identical to the codec encoding of a Vec<u8> holding those bytes. This lets a typed u64 share an on-disk format with a value historically stored as a Vec<u8>.

Implementations

impl VecU64

pub const fn new(value: u64) -> Self

Trait Implementations

impl Clone for VecU64

fn clone(&self) -> VecU64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VecU64

impl Debug for VecU64

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

Formats the value using the given formatter.

impl Default for VecU64

fn default() -> VecU64

Returns the “default value” for a type.

impl EncodeSize for VecU64

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

fn encode_inline_size(&self) -> usize

Returns the encoded size excluding bytes passed to BufsMut::push during Write::write_bufs. Used to size the working buffer for inline writes. Override alongside Write::write_bufs for types where large Bytes fields go via push; failing to do so will over-allocate.

impl Eq for VecU64

impl From<&VecU64> for u64

fn from(value: &VecU64) -> Self

Converts to this type from the input type.

impl From<VecU64> for u64

fn from(value: VecU64) -> Self

Converts to this type from the input type.

impl From<u64> for VecU64

fn from(value: u64) -> Self

Converts to this type from the input type.

impl PartialEq for VecU64

fn eq(&self, other: &VecU64) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Read for VecU64

type Cfg = ()

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, _: &Self::Cfg) -> Result<Self, CodecError>

Reads a value from the buffer using the provided configuration cfg.

impl StructuralPartialEq for VecU64

impl Write for VecU64

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.

fn write_bufs(&self, buf: &mut impl BufsMut)

Writes to a BufsMut, allowing existing Bytes chunks to be appended via BufsMut::push instead of written inline. Must encode to the same format as Write::write. Defaults to Write::write.
