Crate z3_sys

Expand description

§Z3

Z3 is a theorem prover from Microsoft Research.

This crate provides low-level bindings that provide no real affordances for usage from Rust and that mirror the C API.

For bindings that are easier to use from Rust, see the higher level bindings in the Z3 crate.

§Build configuration

This crate needs to locate a Z3 library at build time. The method is controlled by Cargo features and environment variables.

§Features

Feature	Behaviour
(default)	Link against a system-installed Z3 (`brew install z3`, etc.)
`vendored`	Build Z3 from source using `cmake` and statically link it
`bundled`	Deprecated. Alias for `vendored`; will be removed in a future release
`gh-release`	Build against a pre-compiled Z3 static library from GitHub Releases
`vcpkg`	Use a Z3 installed via vcpkg
`bindgen`	Regenerate `functions.rs` from local Z3 headers at build time

§Environment variables

§`vendored` feature

The vendored feature builds Z3 from source using cmake and statically links it. The Z3 source tree is shipped inside the z3-src crate and compiled locally — no network access is required at build time.

By default the Z3 version built is whatever version z3-src bundles. To use a specific version without managing source yourself, gh-release with Z3_SYS_Z3_VERSION is a simpler alternative.

Using your own Z3 checkout: Set Z3_SRC_SOURCE_DIR to the absolute path of a Z3 source tree:

Z3_SRC_SOURCE_DIR=/absolute/path/to/z3 cargo build

To use a project-relative path, add the following to your project’s .cargo/config.toml. The relative = true key tells Cargo to resolve the path relative to the config file’s location:

[env]
Z3_SRC_SOURCE_DIR = { value = "path/to/z3", relative = true }

Note: A z3 directory in your own project or workspace is not picked up automatically — you must set Z3_SRC_SOURCE_DIR explicitly, even if you have a Z3 git submodule in your repo.

§Other variables

Variable	Feature	Description
`Z3_SYS_Z3_HEADER`	`bindgen`	Path to `z3.h`; defaults to `z3-src/z3/src/api/z3.h`
`Z3_SYS_UPDATE_GENERATED`	`bindgen`	Set to `1` to also write `src/generated/functions.rs` and `src/generated/enums.rs`
`Z3_LIBRARY_PATH_OVERRIDE`	default	Add an extra library search path for the linker
`Z3_SYS_Z3_VERSION`	`gh-release`	Z3 version to download (e.g. `4.13.0`)
`READ_ONLY_GITHUB_TOKEN`	`gh-release`	GitHub PAT to avoid API rate limits in CI
`CXXSTDLIB`	any	Override which C++ standard library to link (e.g. `c++`, `stdc++`)

§Example

use z3_sys::*;

unsafe {
    let cfg = Z3_mk_config().unwrap();
    let ctx = Z3_mk_context(cfg).unwrap();

    let a = Z3_mk_not(ctx, Z3_mk_eq(ctx, Z3_mk_false(ctx).unwrap(), Z3_mk_true(ctx).unwrap()).unwrap()).unwrap();
    let b = Z3_mk_not(ctx, Z3_mk_iff(ctx, Z3_mk_false(ctx).unwrap(), Z3_mk_true(ctx).unwrap()).unwrap()).unwrap();
    assert_eq!(Z3_mk_true(ctx), Z3_simplify(ctx, a));
    assert_eq!(Z3_mk_true(ctx), Z3_simplify(ctx, b));

    Z3_del_config(cfg);
    Z3_del_context(ctx);
}

Z3_tactic_repeat^⚠: Return a tactic that keeps applying t until the goal is not modified anymore or the maximum number of iterations max is reached.
Z3_tactic_skip^⚠: Return a tactic that just return the given goal.
Z3_tactic_try_for^⚠: Return a tactic that applies t to a given goal for ms milliseconds. If t does not terminate in ms milliseconds, then it fails.
Z3_tactic_using_params^⚠: Return a tactic that applies t using the given set of parameters.
Z3_tactic_when^⚠: Return a tactic that applies t to a given goal is the probe p evaluates to true. If p evaluates to false, then the new tactic behaves like the skip tactic.
Z3_to_app^⚠: Convert an ast into an APP_AST. This is just type casting.
Z3_to_func_decl^⚠: Convert an AST into a FUNC_DECL_AST. This is just type casting.
Z3_toggle_warning_messages^⚠: Enable/disable printing warning messages to the console.
Z3_translate^⚠: Translate/Copy the AST a from context source to context target. AST a must have been created using context source.
Z3_update_param_value^⚠: Set a value of a context parameter.
Z3_update_term^⚠: Update the arguments of term a using the arguments args. The number of arguments num_args should coincide with the number of arguments to a. If a is a quantifier, then num_args has to be 1.
