indent

Prefixes every non-blank line of s with prefix.

Blank lines (empty or whitespace only) are left untouched, so no trailing whitespace is introduced. Lines are split on '\n' only, and a trailing newline is preserved. It is the inverse of dedent for text indented with a fixed prefix.

Import

use helpers4::string::indent;

cargo add helpers4 --no-default-features --features string

or in Cargo.toml:
