Trait Implementations

impl<'ctx> Ast<'ctx> for Float<'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> where
    Self: Sized, 

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

fn _safe_eq(&self, other: &Self) -> Result<Bool<'ctx>, SortDiffers<'ctx>> where
    Self: Sized, 

Compare this Ast with another Ast, and get a Result. Errors if the sort does not match for the two values.

fn distinct(context: &'ctx Context, values: &[&Self]) -> Bool<'ctx> where
    Self: Sized, 

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 where
    Self: Sized, 

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 where
    Self: Sized,
