pub struct RoundingMode { /* private fields */ }

Ast node representing a rounding mode for Float operations.

Implementations

impl RoundingMode

pub fn round_towards_zero() -> RoundingMode

Create a numeral of RoundingMode sort which represents the TowardZero rounding mode.

pub fn round_towards_negative() -> RoundingMode

Create a numeral of RoundingMode sort which represents the TowardNegative rounding mode.

pub fn round_towards_positive() -> RoundingMode

Create a numeral of RoundingMode sort which represents the TowardPositive rounding mode.

pub fn round_nearest_ties_to_away() -> RoundingMode

Create a numeral of RoundingMode sort which represents the NearestTiesToAway rounding mode.

pub fn round_nearest_ties_to_even() -> RoundingMode

Create a numeral of RoundingMode sort which represents the NearestTiesToEven rounding mode.

pub fn add<A: Into<Float>, B: IntoAst<Float>>(&self, a: A, b: B) -> Float

pub fn sub<A: Into<Float>, B: IntoAst<Float>>(&self, a: A, b: B) -> Float

pub fn mul<A: Into<Float>, B: IntoAst<Float>>(&self, a: A, b: B) -> Float

pub fn div<A: Into<Float>, B: IntoAst<Float>>(&self, a: A, b: B) -> Float

impl RoundingMode

pub fn ast_eq<T: IntoAst<Self>>(&self, other: T) -> bool

where Self: Sized,

pub fn _eq<T: IntoAst<Self>>(&self, other: T) -> Bool

where Self: Sized,

👎Deprecated: Please use eq instead

pub fn ne<T: IntoAst<Self>>(&self, other: T) -> Bool

where Self: Sized,

pub fn eq<T: IntoAst<Self>>(&self, other: T) -> Bool

where Self: Sized,

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

This operation works with all possible Asts (int, real, BV, etc), but the two Asts being compared must be the same type.

pub fn _safe_eq<T: IntoAst<Self>>(&self, other: T) -> Result<Bool, SortDiffers>

where Self: Sized,

👎Deprecated: Please use safe_eq instead

pub fn safe_eq<T: IntoAst<Self>>(&self, other: T) -> Result<Bool, SortDiffers>

where Self: Sized,

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

Trait Implementations

impl Ast for RoundingMode

unsafe fn wrap(ctx: &Context, ast: Z3_ast) -> Self

Wrap a raw Z3_ast.

fn eq<T: IntoAst<Self>>(&self, other: T) -> Bool

where Self: Sized,

fn ne<T: IntoAst<Self>>(&self, other: T) -> Bool

where Self: Sized,

fn get_ctx(&self) -> &Context

fn get_z3_ast(&self) -> Z3_ast

fn distinct(values: &[impl Borrow<Self>]) -> Bool

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

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>(&self, substitutions: &[(&T, &T)]) -> Self

where Self: Sized,

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.

fn num_children(&self) -> usize

Return the number of children of this Ast.

fn nth_child(&self, idx: usize) -> Option<Dynamic>

Return the nth child of this Ast.

fn children(&self) -> Vec<Dynamic>

Return the children of this node as a Vec<Dynamic>.

fn kind(&self) -> AstKind

Return the AstKind for this Ast.

fn is_app(&self) -> bool

Return true if this is a Z3 function application.

fn is_const(&self) -> bool

Return true if this is a Z3 constant.

fn decl(&self) -> FuncDecl

Return the FuncDecl of the Ast.

fn safe_decl(&self) -> Result<FuncDecl, IsNotApp>

fn check_ctx(&self, ctx: &Context)

impl Clone for RoundingMode

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoundingMode

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

Formats the value using the given formatter.

impl Display for RoundingMode

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

Formats the value using the given formatter.

impl Drop for RoundingMode

fn drop(&mut self)

Executes the destructor for this type.

impl From<&RoundingMode> for RoundingMode

fn from(value: &Self) -> Self

Converts to this type from the input type.

impl From<RoundingMode> for Z3_ast

fn from(ast: RoundingMode) -> Self

Converts to this type from the input type.

impl Hash for RoundingMode

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: IntoAst<RoundingMode> + Clone> PartialEq<T> for RoundingMode

fn eq(&self, other: &T) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Solvable for RoundingMode

type ModelInstance = RoundingMode

The type to be extracted from the Solver’s Model.

fn read_from_model( &self, model: &Model, model_completion: bool, ) -> Option<Self::ModelInstance>

fn generate_constraint(&self, model: &Self::ModelInstance) -> Bool

Produce a Bool assertion ruling out the given model from the valuation of self.
