Enum Version

pub enum Version {
    V3,
    V4,
}

The CFB format version to use.

Variants

V3

Version 3, which uses 512-byte sectors.

V4

Version 4, which uses 4096-byte sectors.

Implementations

impl Version

pub fn from_number(number: u16) -> Option<Version>

Returns the version enum for the given version number, or None.

pub fn number(self) -> u16

Returns the version number for this version.

pub fn sector_shift(self) -> u16

Returns the sector shift used in this version.

pub fn sector_len(self) -> usize

Returns the length of sectors used in this version.

use cfb::Version;
assert_eq!(Version::V3.sector_len(), 512);
assert_eq!(Version::V4.sector_len(), 4096);

pub fn stream_len_mask(self) -> u64

Returns the bitmask used for reading stream lengths in this version.

pub fn dir_entries_per_sector(self) -> usize

Returns the number of directory entries per sector in this version.

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Hash for Version

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 Ord for Version

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

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

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