Struct pushgen::generators::SliceGenerator

pub struct SliceGenerator<'a, T> { /* private fields */ }

A generator that generates values from a slice.

Example

let data = [1, 2, 3, 4];
let mut sum = 0;
SliceGenerator::new(&data).for_each(|x| sum += x);
assert_eq!(sum, 10);

Implementations

impl<'a, T> SliceGenerator<'a, T>

pub fn new(slice: &'a [T]) -> Self

Create a new slice generator.

Examples

Basic usage:

use pushgen::SliceGenerator;
let data = [1, 2, 3];
let mut gen = SliceGenerator::new(&data);

Trait Implementations

impl<'a, T: Clone> Clone for SliceGenerator<'a, T>

fn clone(&self) -> SliceGenerator<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T> Generator for SliceGenerator<'a, T>

type Output = &'a T

Data-type generated by the generator.

fn run( &mut self, output: impl FnMut(Self::Output) -> ValueResult ) -> GeneratorResult

Run the generator, emitting values to the output closure.

fn try_advance(&mut self, n: NonZeroUsize) -> (usize, GeneratorResult)

Try to advance the generator n values, ignoring them.

impl<'a, T> ReverseGenerator for SliceGenerator<'a, T>

fn run_back( &mut self, output: impl FnMut(Self::Output) -> ValueResult ) -> GeneratorResult

Run a generator backwards, producing values from the end to the beginning.

fn try_advance_back(&mut self, n: NonZeroUsize) -> (usize, GeneratorResult)

Tries to advance the generator from the back by n values.
