Methods

impl<'ctx> BV<'ctx>

pub fn new_const<S: Into<Symbol>>(
    ctx: &'ctx Context,
    name: S,
    sz: u32
) -> BV<'ctx>

pub fn fresh_const(ctx: &'ctx Context, prefix: &str, sz: u32) -> BV<'ctx>

pub fn from_i64(ctx: &'ctx Context, i: i64, sz: u32) -> BV<'ctx>

pub fn from_u64(ctx: &'ctx Context, u: u64, sz: u32) -> BV<'ctx>

pub fn as_i64(&self) -> Option<i64>

pub fn as_u64(&self) -> Option<u64>

pub fn from_int(ast: &Int<'ctx>, sz: u32) -> BV<'ctx>

Create a bit vector from an integer.

The bit vector will have width sz.

Examples

let i = ast::Int::new_const(&ctx, "x");
solver.assert(&i._eq(&ast::Int::from_i64(&ctx, -3)));

let x = ast::BV::from_int(&i, 64);
assert_eq!(64, x.get_size());

assert_eq!(solver.check(), SatResult::Sat);
let model = solver.get_model();

assert_eq!(-3, model.eval(&x.to_int(true)).unwrap().as_i64().expect("as_i64() shouldn't fail"));

pub fn to_int(&self, signed: bool) -> Int<'ctx>

Trait Implementations

impl<'ctx> Ast<'ctx> for BV<'ctx>

fn new(ctx: &'ctx Context, ast: Z3_ast) -> Self

fn get_ctx(&self) -> &'ctx Context

fn get_z3_ast(&self) -> Z3_ast

fn _eq(&self, other: &Self) -> Bool<'ctx>

Compare this Ast with another Ast, and get a Bool representing the result.
