# Which issue does this PR close?
N/A
# Rationale for this change
`Operator.Reader` accepted no options, unlike `Operator.Writer`. This brings
it to
parity with the Rust core's `Operator::reader_options`.
# What changes are included in this PR?
- **C FFI:** add `opendal_operator_reader_with` and the
`opendal_reader_options` struct
(mirrors core `ReaderOptions`: version, conditional headers,
content-length hint, and
concurrent/chunk/gap/prefetch), with setters and a `From` impl; regenerate
`opendal.h`.
- **Go:** add the `WithReaderFn` option family and `Reader(path string, opts
...WithReaderFn)`;
the `len(opts) == 0` fast path is unchanged.
- Unit, C++, and behavior tests.
# Are there any user-facing changes?
Yes. `Operator.Reader` gains an optional variadic `opts ...WithReaderFn` and
ten `ReaderWith*`
constructors. Existing `op.Reader(path)` calls are unaffected.
# AI Usage Statement
Implemented and reviewed with Claude Code (Claude Opus 4.8) and Codex.
