Struct bitcoin::consensus::encode::VarInt

pub struct VarInt(pub u64);

A variable-length unsigned integer

Methods

impl VarInt

pub fn encoded_length(&self) -> u64

Gets the length of this VarInt when encoded. Returns 1 for 0...0xFC, 3 for 0xFD...(2^16-1), 5 for 0x10000...(2^32-1), and 9 otherwise.

Trait Implementations

impl<S: Encoder> Encodable<S> for VarInt

fn consensus_encode(&self, s: &mut S) -> Result<(), Error>

Encode an object with a well-defined format, should only ever error if the underlying Encoder errors.

impl<D: Decoder> Decodable<D> for VarInt

fn consensus_decode(d: &mut D) -> Result<VarInt, Error>

Decode an object with a well-defined format

impl PartialOrd<VarInt> for VarInt

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

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

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

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

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

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

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

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

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

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

impl PartialEq<VarInt> for VarInt

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

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

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

This method tests for !=.

impl Clone for VarInt

fn clone(&self) -> VarInt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for VarInt

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.

impl Eq for VarInt

impl Debug for VarInt

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

Formats the value using the given formatter.
