Struct breez_sdk_liquid::lightning::util::ser::BigSize

pub struct BigSize(pub u64);

Lightning TLV uses a custom variable-length integer called BigSize. It is similar to Bitcoin’s variable-length integers except that it is serialized in big-endian instead of little-endian.

Like Bitcoin’s variable-length integer, it exhibits ambiguity in that certain values can be encoded in several different ways, which we must check for at deserialization-time. Thus, if you’re looking for an example of a variable-length integer to use for your own project, move along, this is a rather poor design.

Trait Implementations

impl Clone for BigSize

fn clone(&self) -> BigSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BigSize

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

Formats the value using the given formatter.

impl Hash for BigSize

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

where __H: Hasher,

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 Ord for BigSize

fn cmp(&self, other: &BigSize) -> 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 BigSize

fn eq(&self, other: &BigSize) -> 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 PartialOrd for BigSize

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Readable for BigSize

fn read<R>(reader: &mut R) -> Result<BigSize, DecodeError>

where R: Read,

Reads a Self in from the given Read.

impl Writeable for BigSize

fn write<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Writer,

Writes self out to the given Writer.

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

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.

impl Copy for BigSize

impl Eq for BigSize

impl StructuralPartialEq for BigSize
