simdjson-sys

Low-level CXX bindings to the simdjson v4.6.4 DOM parser. Version 0.4.0-alpha.2 accompanies simdjson-rust 0.4.0-alpha.2.

Requires Rust 1.88+, CMake 3.15+, and a C++17 compiler (C++20 for MSVC targets). The published crate bundles unmodified upstream singleheader sources; the C++ build does not need network access. See vendor/simdjson/README.md for the upstream revision and vendor/simdjson/LICENSE for its Apache-2.0 license. These Rust bindings are also Apache-2.0; see LICENSE.txt.

Safety

parser_parse is unsafe. When realloc_if_needed is false, the allocation must provide at least 64 initialized readable bytes beyond the input slice. With true, simdjson copies the input into its own padded buffer.

parser_get_tape_view is unsafe and requires a successful last parse, without subsequent parser mutation. The returned slices borrow the parser and expose only initialized tape and string-buffer contents. Use simdjson-rust::dom::Parser for a safe API that tracks parser validity and handles padding.

The optional native feature enables -march=native for the library and bridge on non-MSVC targets. Leave it disabled when distributing portable binaries.
