Struct z3::ast::Int

pub struct Int<'ctx> { /* fields omitted */ }

Ast node representing an integer value.

Methods

impl<'ctx> Int<'ctx>

pub fn from_str(ctx: &'ctx Context, value: &str) -> Option<Int<'ctx>>

impl<'ctx> Int<'ctx>

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

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

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

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

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

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

pub fn from_real(ast: &Real<'ctx>) -> Int<'ctx>

pub fn to_real(&self) -> Real<'ctx>

Create a real from an integer. This is just a convenience wrapper around Real::from_int; see notes there

pub fn from_bv(ast: &BV<'ctx>, signed: bool) -> Int<'ctx>

Create an integer from a bitvector.

Signed and unsigned version.

Examples

let bv = ast::BV::new_const(&ctx, "x", 32);
solver.assert(&bv._eq(&ast::BV::from_i64(&ctx, -3, 32)));

let x = ast::Int::from_bv(&bv, true);

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

assert_eq!(-3, model.eval(&x).unwrap().as_i64().unwrap());

pub fn to_ast(&self, sz: u32) -> BV<'ctx>

Create a bitvector from an integer. This is just a convenience wrapper around BV::from_int; see notes there

Trait Implementations

impl<'ctx> Ast<'ctx> for Int<'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.

fn distinct(&self, other: &[&Self]) -> Bool<'ctx>

Compare this Ast with a list of other Asts, and get a Bool which is true only if all arguments (including Self) are pairwise distinct.

fn get_sort(&self) -> Sort<'ctx>

Get the Sort of the Ast

fn simplify(&self) -> Self

Simplify the Ast. Returns a new Ast which is equivalent, but simplified using algebraic simplification rules, such as constant propagation.

fn substitute<T: Ast<'ctx>>(&self, substitutions: &[(&T, &T)]) -> Self

Performs substitution on the Ast. The slice substitutions contains a list of pairs with a "from" Ast that will be substituted by a "to" Ast.

impl<'ctx> From<Int<'ctx>> for Z3_ast

fn from(ast: Int<'ctx>) -> Self

Performs the conversion.

impl<'ctx> From<Int<'ctx>> for Dynamic<'ctx>

fn from(ast: Int<'ctx>) -> Self

Performs the conversion.

impl<'ctx> Drop for Int<'ctx>

fn drop(&mut self)

Executes the destructor for this type.

impl<'ctx> PartialEq<Int<'ctx>> for Int<'ctx>

fn eq(&self, other: &Int<'ctx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'ctx> Clone for Int<'ctx>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
