[][src]Struct gf::smt::ConstExpr

pub struct ConstExpr { /* fields omitted */ }

Expression that can be evaluated to a constant value.


This example calculates the expression 5 * (4 + 6) using 32-bit integers.

let expr = Expr::new_bit_vec_operator(
assert_eq!(ConstExpr::new(expr)?.eval(), ExprValue::BitVec(50u32.into()));


impl ConstExpr[src]

pub fn new(expr: Expr) -> Result<Self, ExprError>[src]

Wrap an expression, checking that it is constant-evaluatable.

pub unsafe fn new_unchecked(expr: Expr) -> Self[src]

Wrap an expression skipping the checks.

pub fn from_value(value: ExprValue) -> Self[src]

Wrap a value.

pub fn into_inner(self) -> Expr[src]

Consume the wrapper and return the underlying expression.

pub fn is_const_expr(expr: &Expr) -> bool[src]

Check if an expression is constant-evaluatable.

pub fn eval(&self) -> ExprValue[src]

Evaluate the expression.
