Enum hyperx::header::ByteRangeSpec [−][src]
Expand description
Each Range::Bytes
header can contain one or more ByteRangeSpecs
.
Each ByteRangeSpec
defines a range of bytes to fetch
Variants
Get all bytes between x and y (“x-y”)
AllFrom(u64)
Get all bytes starting from x (“x-”)
Tuple Fields of AllFrom
0: u64
Last(u64)
Get last x bytes (“-x”)
Tuple Fields of Last
0: u64
Implementations
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).
