Trait Implementations

impl Clone for PointerBlock

pub fn clone(&self) -> PointerBlock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for PointerBlock

impl Debug for PointerBlock

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

Formats the value using the given formatter.

impl Default for PointerBlock

pub fn default() -> Self

Returns the "default value" for a type.

impl Eq for PointerBlock

impl From<[Option<Pointer>; 256]> for PointerBlock

pub fn from(src: PointerBlockArray) -> Self

Performs the conversion.

impl FromBytes for PointerBlock

pub fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

pub fn from_vec(
    bytes: Vec<u8, Global>
) -> Result<(Self, Vec<u8, Global>), Error>

Deserializes the Vec<u8> into Self.

impl Index<Range<usize>> for PointerBlock

type Output = [PointerBlockValue]

The returned type after indexing.

pub fn index(&self, index: Range<usize>) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<RangeFrom<usize>> for PointerBlock

type Output = [PointerBlockValue]

The returned type after indexing.

pub fn index(&self, index: RangeFrom<usize>) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<RangeFull> for PointerBlock

type Output = [PointerBlockValue]

The returned type after indexing.

pub fn index(&self, index: RangeFull) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<RangeTo<usize>> for PointerBlock

type Output = [PointerBlockValue]

The returned type after indexing.

pub fn index(&self, index: RangeTo<usize>) -> &[PointerBlockValue]

Performs the indexing (container[index]) operation.

impl Index<usize> for PointerBlock

type Output = PointerBlockValue

The returned type after indexing.

pub fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for PointerBlock

pub fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq<PointerBlock> for PointerBlock

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl ToBytes for PointerBlock

pub fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

pub fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

pub fn into_bytes(self) -> Result<Vec<u8, Global>, Error>

Consumes self and serializes to a Vec<u8>.
