Struct CompactInt 

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

A Bitcoin-formatted CompactInt

Implementations

impl CompactInt

pub fn parse<T: AsRef<[u8]> + ?Sized>(t: &T) -> Result<CompactInt, SPVError>

Parse a compact int from a byte slice

pub fn number(&self) -> u64

Return the underlying u64

pub fn as_usize(&self) -> usize

The underlying number as a usize

pub fn serialized_length(&self) -> usize

Determine the length of the compact int when serialized

pub fn data_length(flag: u8) -> u8

Determines the length of a CompactInt in bytes. A CompactInt of > 1 byte is prefixed with a flag indicating its length.

Arguments

• flag - The first byte of a compact_int

impl Ord for CompactInt

fn cmp(&self, other: &CompactInt) -> 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.
