Enum FormatVersion 

#[repr(u8)]
pub enum FormatVersion {
    V1 = 1,
    V2 = 2,
}

Block format version

Variants

V1 = 1

Original format (17-byte header)

V2 = 2

Extended format (21-byte header with flags)

Implementations

impl FormatVersion

pub const CURRENT: FormatVersion = FormatVersion::V2

Current format version used for new blocks

pub fn from_byte(b: u8) -> Option<Self>

Parse from byte

pub fn header_size(&self) -> usize

Get header size for this version

Trait Implementations

impl Clone for FormatVersion

fn clone(&self) -> FormatVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatVersion

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

Formats the value using the given formatter.

impl Ord for FormatVersion

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

Restrict a value to a certain interval.

impl PartialEq for FormatVersion

fn eq(&self, other: &FormatVersion) -> 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 FormatVersion

fn partial_cmp(&self, other: &FormatVersion) -> 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.
