Enum ByteRangeSpec 

pub enum ByteRangeSpec {
    FromTo(u64, u64),
    AllFrom(u64),
    Last(u64),
}

A single entry of a Range header’s byte-range-set, as defined in RFC7233 §2.1.

Variants

FromTo(u64, u64)

first-last: an inclusive range from first to last.

AllFrom(u64)

first-: from first to the end of the representation.

Last(u64)

-suffix: the final suffix bytes of the representation.

Implementations

impl ByteRangeSpec

pub fn to_satisfiable_range(&self, content_length: u64) -> Option<(u64, u64)>

Resolve this spec against a known content_length into an inclusive (first, last) byte range, following RFC7233 §2.1.

The end is clamped to content_length - 1, a suffix (-n) range is anchored to the end of the representation (a suffix at least as long as the representation yields the whole of it), and None is returned when the range is unsatisfiable — the cue for a 416 Range Not Satisfiable response. A returned range always satisfies 0 <= first <= last < content_length.

Trait Implementations

impl Clone for ByteRangeSpec

fn clone(&self) -> ByteRangeSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ByteRangeSpec

impl Debug for ByteRangeSpec

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

Formats the value using the given formatter.

impl Display for ByteRangeSpec

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

Formats the value using the given formatter.

impl Eq for ByteRangeSpec

impl Hash for ByteRangeSpec

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 PartialEq for ByteRangeSpec

fn eq(&self, other: &ByteRangeSpec) -> 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.
