Required Methods§

Source

fn all<F>(self, f: F) -> bool
where F: FnMut(Self::Item) -> bool,

Checks if every element of tuple matches a predicate, like std::iter::Iterator::all.

This method take a closure returns true or false, and tries to apply this closure to all elements of tuple. If and only if all of them returns true, this method return true.

§Examples
ⓘ
let a = (3, 9, 12, ...);
assert!(a.all(|x| x % 3 == 0));
assert!(!a.all(|x| x % 4 == 0));
Source

fn any<F>(self, f: F) -> bool
where F: FnMut(Self::Item) -> bool,

Checks if any element of tuple matches a predicate, like std::iter::Iterator::any.

This method take a closure returns true or false, and tries to apply this closure to all elements of tuple. If any of them returns true, this method return true.

§Examples
ⓘ
let a = (3, 9, 12, ...);
assert!(a.any(|x| x % 4 == 0));
assert!(!a.any(|x| x % 7 == 0));
Source

fn by_ref( &self, ) -> (&Self::Item, &Self::Item, &Self::Item, &Self::Item, &Self::Item, &Self::Item, &Self::Item, &Self::Item, &Self::Item)

Takes &(a, a, a, ...) and returns (&a, &a, &a, ...)

§Examples
ⓘ
let a = (3, 3, 3, ...);
assert_eq!(a.by_ref(), (&3, &3, &3, ...));
Source

fn by_ref_mut( &mut self, ) -> (&mut Self::Item, &mut Self::Item, &mut Self::Item, &mut Self::Item, &mut Self::Item, &mut Self::Item, &mut Self::Item, &mut Self::Item, &mut Self::Item)

Takes &mut (a, a, a, ...) and returns (&mut a, &mut a, &mut a, ...)

§Examples
ⓘ
let a = (3, 3, 3, ...);
assert_eq!(a.by_ref(), (&mut 3, &mut 3, &mut 3, ...));
Source

fn find<F>(self, f: F) -> Option<Self::Item>
where F: FnMut(&Self::Item) -> bool,

Find the leftest element which satisfies f and returns it.

§Example
ⓘ
let mut a = (3, 3, 5, 3, ...);
if let Some(x) = a.by_ref_mut().find(|&&mut x| x == 5) {
    *x = 3
}
assert!(a.same());
Source

fn fold<B, F>(self, init: B, f: F) -> B
where F: FnMut(B, Self::Item) -> B,

Takes a closure f and applies it to all elements to tuple, and produce single value. This is similar to std::iter::Iterator::fold

§Example
ⓘ
let a = (3, 4, 5, ...)
let sum = a.fold(0, |sum, x| sum + x);
Source

fn for_each<F>(self, f: F)
where F: FnMut(Self::Item),

Takes a closure f and applies it to all elements to tuple. f can cause side effect(because it’s FnMut), but this method return nothing. Similar to std::iter::Iterator::for_each

§Example
ⓘ
let a = (3, 4, 5, ...);
let mut sum = 0;
a.for_each(|x| sum += x);
Source

fn id( self, ) -> (Self::Item, Self::Item, Self::Item, Self::Item, Self::Item, Self::Item, Self::Item, Self::Item, Self::Item)

return Self. It’s not intended to used by user.

Source

fn into_vec(self) -> Vec<Self::Item>

Convert tuple into Vec.

§Example
ⓘ
let a = (3, 4, 5, ...)
assert_eq(a.into_vec(), vec![3, 4, 5, ...])
Source

fn map<B, F>(self, f: F) -> (B, B, B, B, B, B, B, B, B)
where F: FnMut(Self::Item) -> B,

Takes a closure f and (a, a, a, …), then returns (f(a), f(a), f(a), …). Similar to std::iter::Iterator::map.

§Example
ⓘ
let a = (3, 4, 5, ...);
assert_eq!(a.map(|x| x * 2), (6, 8, 10, ...));
Source

fn nth(self, i: usize) -> Option<Self::Item>

return nth element in the tuple.

§Example
ⓘ
let a = (3, 4, 5, ..);
assert_eq!(a.nth(2), Some(5));
Source

fn same(self) -> bool
where Self::Item: PartialEq,

Checks if all elements of the tuple is same.

§Example
ⓘ
let a = (3, 3, 3, ...);
assert!(a.same());
Source

fn same_as(self, i: Self::Item) -> bool
where Self::Item: PartialEq,

Takes i and checks if all elements of the tuple is same as i.

§Example
ⓘ
let a = (3, 3, 3, ...);
assert!(a.same_as(3));
Source

fn sum(self) -> Self::Item
where Self::Item: AddAssign,

Takes (a, b, c, ...) then returns a + b + c ...

Source

fn product(self) -> Self::Item
where Self::Item: MulAssign,

Takes (a, b, c, ...) then returns a + b + c ...

Source

fn tmax(self) -> Self::Item
where Self::Item: PartialOrd,

Takes (a, b, c, ...) then returns the maximum value of tuple. This method is named tmax instead of max, to avoid overlap to std::cmp::ord::max.

Source

fn tmin(self) -> Self::Item
where Self::Item: PartialOrd,

Takes (a, b, c, ...) then returns the minimum value of tuple. This method is named tmin instead of min, to avoid overlap to std::cmp::ord::min.

Source

fn zip<U, B>( self, other: U, ) -> ((Self::Item, B), (Self::Item, B), (Self::Item, B), (Self::Item, B), (Self::Item, B), (Self::Item, B), (Self::Item, B), (Self::Item, B), (Self::Item, B))
where U: TupleMap9<Item = B>,

Takes (a, a, a, ...) and (b, b, b, ...) then returns ((a, b), (a, b), (a, b), ...)

§Example
ⓘ
let a = (3, 4, 5, ...);
let b = ('a', 'b', 'c', ...);
assert_eq!(a.zip(b), ((3, 'a'), (4, 'b'), (5, 'c'), ...));

ⓘ
let a = (3, 4, 5, ...);
let b = ('a', 'b', 'c', ...);
assert_eq!(
    a.zipf(b, |x, y| format!("{}{}", x, y)),
    ("3a", "4b", "5c", ...).map(|x| x.to_owned())
);

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
