Enum hyper::header::ByteRangeSpec
[−]
[src]
pub enum ByteRangeSpec {
FromTo(u64, u64),
AllFrom(u64),
Last(u64),
}Each Range::Bytes header can contain one or more ByteRangeSpecs.
Each ByteRangeSpec defines a range of bytes to fetch
Variants
FromTo(u64, u64)Get all bytes between x and y ("x-y")
AllFrom(u64)Get all bytes starting from x ("x-")
Last(u64)Get last x bytes ("-x")
Methods
impl ByteRangeSpec[src]
pub fn to_satisfiable_range(&self, full_length: u64) -> Option<(u64, u64)>[src]
Given the full length of the entity, attempt to normalize the byte range into an satisfiable end-inclusive (from, to) range.
The resulting range is guaranteed to be a satisfiable range within the bounds
of 0 <= from <= to < full_length.
If the byte range is deemed unsatisfiable, None is returned.
An unsatisfiable range is generally cause for a server to either reject
the client request with a 416 Range Not Satisfiable status code, or to
simply ignore the range header and serve the full entity using a 200 OK
status code.
This function closely follows RFC 7233 section 2.1. As such, it considers ranges to be satisfiable if they meet the following conditions:
If a valid byte-range-set includes at least one byte-range-spec with a first-byte-pos that is less than the current length of the representation, or at least one suffix-byte-range-spec with a non-zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable.
The function also computes remainder ranges based on the RFC:
If the last-byte-pos value is absent, or if the value is greater than or equal to the current length of the representation data, the byte range is interpreted as the remainder of the representation (i.e., the server replaces the value of last-byte-pos with a value that is one less than the current length of the selected representation).
