Struct z3::ast::Array

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

Ast node representing an array value. An array in Z3 is a mapping from indices to values.

Methods

impl<'ctx> Array<'ctx>

pub fn new_const<S: Into<Symbol>>(
    ctx: &'ctx Context,
    name: S,
    domain: &Sort<'ctx>,
    range: &Sort<'ctx>
) -> Array<'ctx>

Create an Array which maps from indices of the domain Sort to values of the range Sort.

All values in the Array will be unconstrained.

pub fn fresh_const(
    ctx: &'ctx Context,
    prefix: &str,
    domain: &Sort<'ctx>,
    range: &Sort<'ctx>
) -> Array<'ctx>

pub fn const_array(
    ctx: &'ctx Context,
    domain: &Sort<'ctx>,
    val: &Dynamic<'ctx>
) -> Array<'ctx>

Create a "constant array", that is, an Array initialized so that all of the indices in the domain map to the given value val

pub fn translate<'dest_ctx>(&self, dest: &'dest_ctx Context) -> Array<'dest_ctx>

pub fn select(&self, index: &Dynamic<'ctx>) -> Dynamic<'ctx>

Get the value at a given index in the array.

Note that the index must be of the array's domain sort. The return type will be of the array's range sort.

pub fn store(&self, index: &Dynamic<'ctx>, value: &Dynamic<'ctx>) -> Self

Update the value at a given index in the array.

Note that the index must be of the array's domain sort, and the value must be of the array's range sort.

Trait Implementations

impl<'ctx> Ast<'ctx> for Array<'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> Clone for Array<'ctx>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'ctx> Drop for Array<'ctx>

fn drop(&mut self)

Executes the destructor for this type.

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

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

Performs the conversion.

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

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

Performs the conversion.

impl<'ctx> Eq for Array<'ctx>

impl<'ctx> PartialEq<Array<'ctx>> for Array<'ctx>

fn eq(&self, other: &Array<'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> Hash for Array<'ctx>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl<'ctx> Display for Array<'ctx>

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<'ctx> Debug for Array<'ctx>

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<'ctx> TryFrom<Dynamic<'ctx>> for Array<'ctx>

type Error = String

The type returned in the event of a conversion error.

fn try_from(ast: Dynamic<'ctx>) -> Result<Self, String>

Performs the conversion.
