Crate display_utils

This library provides several useful constructs to format data in a human-readable fashion with zero allocations

Some of these functions may seem to partly reinvent existing std functionality, for example join:

println!("{}", display_utils::join(&[1, 2, 3], " + ")); // display_utils
println!("{}", ["1", "2", "3"].join(" + ")); // std
 
println!("{}", display_utils::repeat("abc", 4)); // display_utils
println!("{}", "abc".repeat(4)); // std

The important difference is that the std approach involves 4 allocations, whereas the display_utils approach operates 100% on stack and is therefore no_std compatible and likely faster.

Functions

concat	Concatenate the contents of an iterator.
indent_4	Indent to a given depth using 4 spaces.
indent_tab	Indent to a given depth using the tab character.
join	Concatenate iterator elements, separating each element pair with a given joiner.
join_format	Concatenate iterator elements, separating each element pair with a given joiner, where each iterator element can be formatted using a callback.
lowercase	Print a Unicode-compliant lowercase version of the string.
repeat	Repeat an object a certain number of times.
replace	Replace instances of the from string with the to string.
replace_n	Replace the first n instances of the from string with the to string.
unicode_block_bar	Print a loading-style bar using Unicode block characters.
uppercase	Print a Unicode-compliant uppercase version of the string.
vertical_unicode_block_bars	Print a sequence of equalizer-style vertical bars using Unicode block characters.
