dedent

Strips the indentation shared by every non-blank line of s, and drops one leading and one trailing blank line.

Lets a multi-line string literal be indented with the surrounding code without that indentation leaking into the value. Indentation is counted in whitespace characters, and lines are split on '\n' only (a '\r' stays on its line).

Import

use helpers4::string::dedent;

Cargo feature string (enabled by default). To compile only this module:

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

or in Cargo.toml:

[dependencies]
helpers4 = { version = "0.0.5", default-features = false, features = ["string"] }

Signature

pub fn dedent(s: &str) -> String

Parameters

Parameter	Type	Description
s	&str	The text to strip the shared indentation from.

Returns

String

Examples

use helpers4::string::dedent;

assert_eq!(dedent("\n    Hello\n      World\n"), "Hello\n  World");
assert_eq!(dedent("  a\n  b"), "a\nb");
