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 asf32).sqrt()).printerd(),);

# use printerator::PrinterateDisplay;let data = "Hello, w🌍rld!";letmut 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,item30: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
