string_morph

string_morph is a Rust library of string case transformations with an emphasis on accuracy and performance. The case conversions are available as functions as well as traits on String types.

Examples

  use string_morph::Morph;

  // Camel case
  assert_eq!("loremIpsumDolor", string_morph::to_camel_case("lorem_ipsum_dolor"));
  assert_eq!("loremIpsumDolor", "lorem_ipsum_dolor".to_camel_case());

  // Pascal case
  assert_eq!("LoremIpsumDolor", string_morph::to_pascal_case("lorem_ipsum_dolor"));
  assert_eq!("LoremIpsumDolor", "lorem_ipsum_dolor".to_pascal_case());

  // Kebab case
  assert_eq!("lorem-ipsum-dolor", string_morph::to_kebab_case("lorem_ipsum_dolor"));
  assert_eq!("lorem-ipsum-dolor", "lorem_ipsum_dolor".to_kebab_case());

  // Sentence case
  assert_eq!("Lorem ipsum dolor", string_morph::to_sentence_case("lorem_ipsum_dolor"));
  assert_eq!("Lorem ipsum dolor", "lorem_ipsum_dolor".to_sentence_case());

  // Snake case
  assert_eq!("lorem_ipsum_dolor", string_morph::to_snake_case("Lorem ipsum dolor"));
  assert_eq!("lorem_ipsum_dolor", "Lorem ipsum dolor".to_snake_case());

  // Upper snake case
  assert_eq!("LOREM_IPSUM_DOLOR", string_morph::to_snake_caps_case("Lorem ipsum dolor"));
  assert_eq!("LOREM_IPSUM_DOLOR", "Lorem ipsum dolor".to_snake_caps_case());

  // Title case
  assert_eq!("Lorem Ipsum Dolor", string_morph::to_title_case("lorem-ipsum-dolor"));
  assert_eq!("Lorem Ipsum Dolor", "lorem-ipsum-dolor".to_title_case());

  // Upper first
  assert_eq!("Test", string_morph::to_upper_first("test"));
  assert_eq!("Test", "test".to_upper_first());
