fn borrow_mut(&mut self) -> &mut u32

Mutably borrows from an owned value.

impl Clone for BlockHeight

fn clone(&self) -> BlockHeight

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockHeight

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

Formats the value using the given formatter.

impl Default for BlockHeight

fn default() -> BlockHeight

Returns the “default value” for a type.

impl Deref for BlockHeight

type Target = u32

The resulting type after dereferencing.

fn deref(&self) -> &u32

Dereferences the value.

impl DerefMut for BlockHeight

fn deref_mut(&mut self) -> &mut u32

impl Deserialize for BlockHeight

fn decode_static<I: Input + ?Sized>(buffer: &mut I) -> Result<Self, Error>

Decodes static part of Self from the buffer.

fn decode_dynamic<I: Input + ?Sized>( &mut self, buffer: &mut I, ) -> Result<(), Error>

Decodes dynamic part of the information from the buffer to fill Self. The default implementation does nothing. Dynamically-sized contains should override this.

fn decode<I: Input + ?Sized>(buffer: &mut I) -> Result<Self, Error>

Decodes Self from the buffer.

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

Helper method for deserializing Self from bytes.

impl Display for BlockHeight

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

Formats the value using the given formatter.

impl From<[u8; 4]> for BlockHeight

fn from(bytes: [u8; 4]) -> Self

Converts to this type from the input type.

impl From<BlockHeight> for [u8; 4]

fn from(salt: BlockHeight) -> [u8; 4]

Converts to this type from the input type.

impl From<BlockHeight> for u32

fn from(salt: BlockHeight) -> u32

Converts to this type from the input type.

impl From<u32> for BlockHeight

fn from(value: u32) -> Self

Converts to this type from the input type.

impl FromStr for BlockHeight

type Err = &'static str

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for BlockHeight

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for BlockHeight

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

Formats the value using the given formatter.

impl Ord for BlockHeight

fn cmp(&self, other: &BlockHeight) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for BlockHeight

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for BlockHeight

fn partial_cmp(&self, other: &BlockHeight) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for BlockHeight

fn size_static(&self) -> usize

Size of the static part of the serialized object, in bytes. Saturates to usize::MAX on overflow.

fn size_dynamic(&self) -> usize

Size of the dynamic part, in bytes. Saturates to usize::MAX on overflow.

fn encode_static<O: Output + ?Sized>(&self, buffer: &mut O) -> Result<(), Error>
