Struct BoxBrand 

pub struct BoxBrand;

Brand for Box owned heap-allocated pointer.

BoxBrand implements Pointer and ToDynFn but not RefCountedPointer (since Box<dyn Fn> is not Clone).

Trait Implementations

impl Clone for BoxBrand

fn clone(&self) -> BoxBrand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoxBrand

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

Formats the value using the given formatter.

impl Default for BoxBrand

fn default() -> BoxBrand

Returns the “default value” for a type.

impl Hash for BoxBrand

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 Ord for BoxBrand

fn cmp(&self, other: &BoxBrand) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BoxBrand

fn eq(&self, other: &BoxBrand) -> 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 PartialOrd for BoxBrand

fn partial_cmp(&self, other: &BoxBrand) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Pointer for BoxBrand

fn new<'a, T: 'a>(value: T) -> Box<T>

Wraps a sized value in a Box.

Type Signature

forall T. T -> T

Type Parameters

• 'a: The lifetime of the value.
• T: The type of the value to wrap.

Parameters

• value: The value to wrap.

Returns

The value wrapped in a Box.

Examples

use fp_library::{
	brands::*,
	classes::*,
};

let ptr = <BoxBrand as Pointer>::new(42);
assert_eq!(*ptr, 42);

type Of<'a, T: ?Sized + 'a> = Box<T>

The pointer type constructor.

impl ToDynFn for BoxBrand

fn new<'a, A: 'a, B: 'a>(f: impl 'a + Fn(A) -> B) -> Box<dyn Fn(A) -> B + 'a>

Coerces a sized closure to a dyn Fn wrapped in a Box.

Type Signature

forall A B. (A -> B) -> A -> B

Type Parameters

• 'a: The lifetime of the closure.
• A: The input type of the function.
• B: The output type of the function.

Parameters

• f: The closure to coerce.

Returns

The closure wrapped in a Box as a trait object.

Examples

use fp_library::{
	brands::*,
	classes::*,
};

let f = <BoxBrand as ToDynFn>::new(|x: i32| x + 1);
assert_eq!(f(1), 2);

fn ref_new<'a, A: 'a, B: 'a>( f: impl 'a + Fn(&A) -> B, ) -> Box<dyn Fn(&A) -> B + 'a>

Coerces a sized by-reference closure to a dyn Fn(&A) -> B wrapped in a Box.

Type Signature

forall A B. (&A -> B) -> &A -> B

Type Parameters

• 'a: The lifetime of the closure.
• A: The input type (the closure receives &A).
• B: The output type of the function.

Parameters

• f: The closure to coerce.

Returns

The closure wrapped in a Box as a by-reference trait object.

Examples

use fp_library::{
	brands::*,
	classes::*,
};

let f = <BoxBrand as ToDynFn>::ref_new(|x: &i32| *x + 1);
assert_eq!(f(&1), 2);
