impl Clone for CompactU256

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compact for CompactU256

fn to_compact<B>(&self, buf: &mut B) -> usize

fn specialized_to_compact<B>(&self, buf: &mut B) -> usize

where B: BufMut + AsMut<[u8]>,

“Optional”: If there’s no good reason to use it, don’t.

fn specialized_from_compact(buf: &[u8], len: usize) -> (Self, &[u8])

“Optional”: If there’s no good reason to use it, don’t.

impl Compress for CompactU256

type Compressed = Vec<u8>

Compressed type.

fn compress_to_buf<B: BufMut + AsMut<[u8]>>(&self, buf: &mut B)

Compresses data to a given buffer.

fn uncompressable_ref(&self) -> Option<&[u8]>

If the type cannot be compressed, return its inner reference as Some(self.as_ref())

fn compress(self) -> Self::Compressed

Compresses data going into the database.

impl Debug for CompactU256

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

Formats the value using the given formatter.

impl Decompress for CompactU256

fn decompress(value: &[u8]) -> Result<CompactU256, DecompressError>

Decompresses data coming from the database.

fn decompress_owned(value: Vec<u8>) -> Result<Self, DecompressError>

Decompresses owned data coming from the database.

impl Default for CompactU256

fn default() -> Self

Returns the “default value” for a type.

impl Deref for CompactU256

type Target = Uint<256, 4>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
