printerator

Print iterators without having to collect them.

Examples

# use printerator::PrinterateDebug;
let ints: [u32; 3] = [0xcafebabe, 0xabad1dea, 0xdeadc0de];
println!(
    "{:.1?}",
    ints.iter().map(|&int| (int as f32).sqrt()).printerd(),
);

# use printerator::PrinterateDisplay;
let data = "Hello, w🌍rld!";
let mut nonascii_iter = data.bytes().enumerate().filter(|&(_, b)| b >= 128);
println!(
    "Invalid ascii byte indices: {}",
    nonascii_iter.clone().map(|(i, _)| i).printer_with_options(false, false),
);

Available in 2 flavors: A debug printer, and a display printer, both of which are createble over any iterator whose item is implementing either [Debug] or [Display], using the methods printerd and printer respectively.

Formatting options are passed as-is to the [Iterator::Item]'s implementation of [Debug] and [Display]. That means you should pass them in as if you were formatting 1 single item.

printer{d}_with_options arguments:

• pretty: true if you want newlines and brackets:

[
    item,
    item2,
    item3
]
[
    0: item,
    1: item2
]

otherwise, false:

item, item2, item3
0: item, 1: item2

• indices: true if you want the indices too:

[
    0: item,
    1: item2
]
0: item, 1: item2, 2: item3

otherwise, false:

[
    item,
    item2
]
item, item2
