Implementations

impl ByteRange

pub fn from_to(start: u64, end: u64) -> Result<Self, RangeError>

Create a range from start to end (inclusive)

pub fn from(start: u64) -> Self

Create a range from offset to end

pub fn suffix(count: u64) -> Self

Create a range for the last N bytes

pub fn to_range(&self, total_size: u64) -> Result<Range<u64>, RangeError>

Convert to concrete byte range given total size

pub fn overlaps(&self, other: &ByteRange, total_size: u64) -> bool

Check if this range overlaps with another

pub fn merge(&self, other: &ByteRange, total_size: u64) -> Option<ByteRange>

Merge two ranges if they overlap or are adjacent

pub fn size(&self, total_size: u64) -> u64

Get the size of this range

Trait Implementations

impl Clone for ByteRange

fn clone(&self) -> ByteRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ByteRange

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ByteRange

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ByteRange

fn eq(&self, other: &ByteRange) -> 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 Serialize for ByteRange

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
