EqualFold, IndexFold, ContainsFold, HasPrefixFold, and
HasSuffixFold compare ASCII case-insensitively using the SWAR word
loops: only A..Z/a..z fold, every other byte (including bytes
= 0x80) must match exactly.
HasPrefixFoldandHasSuffixFoldcover the header checks Fiber otherwise spells as an allocation-proneToLower+HasPrefix/HasSuffixpair (authorization schemes such asBearer, content-type prefixes such asmultipart/form-data, suffixes such as+json), and like the other Fold helpers they take the needle as a plain string because call sites pass constant tokens. TheirBenchmark_HasPrefixFold/Benchmark_HasSuffixFoldnumbers are tracked on the benchmark charts and join the catalog above on its next regeneration.
The swar package exports the SWAR (SIMD within a register)
building blocks the helpers above are composed from: Load8/Store8,
Broadcast, ZeroLanes, MatchByteMask/MatchRangeMask,
ToLowerWord/ToUpperWord, FirstLane/LastLane, and the WordLen,
Ones, HighBits, and LowSeven constants. They are exported so
downstream packages (Fiber itself, middleware) can fuse their own byte
scans — for example, finding a delimiter while classifying the bytes
before it — without re-deriving the bit tricks. The contracts (unchecked
bounds preconditions, ZeroLanes' approximate mask, the little-endian
lane order) and runnable examples live in the package documentation.
The package benchmarks its primitives against their stdlib counterparts
the same way the helpers above do, measuring the canonical loops composed
from them: Load8/Store8 vs encoding/binary's little-endian
Uint64/PutUint64, a ZeroLanes first-match scan vs
strings.IndexByte, a MatchByteMask+LastLane reverse scan vs
bytes.LastIndexByte, a MatchRangeMask digit scan vs
strings.IndexAny, and an in-place ToLowerWord loop vs
bytes.ToLower. The composed loops are pinned to the stdlib results by a
dedicated test, and the numbers are tracked per commit on the
benchmark charts. Note
that strings.IndexByte is hand-written SIMD assembly and overtakes the
portable SWAR scan on large inputs; the SWAR primitives earn their keep
on short HTTP-sized inputs and on fused scans the stdlib has no single
function for. The package's remaining benchmark, Benchmark_Load8_Fusion,
is an advisory codegen guard rather than an API performance promise, so
it is deliberately not part of the catalog above.
