Defines the type of casing a string can be.

let super_mario_title: String = "super_mario_64".to_case(Case::Title);
assert_eq!("Super Mario 64", super_mario_title);

Variants

Upper

Uppercase strings are delimited by spaces and all characters are uppercase.

use convert_case::{Case, Casing};
assert_eq!("MY VARIABLE NAME", "My variable NAME".to_case(Case::Upper))

Lower

Lowercase strings are delimited by spaces and all characters are lowercase.

use convert_case::{Case, Casing};
assert_eq!("my variable name", "My variable NAME".to_case(Case::Lower))

Title

Title case strings are delimited by spaces. Only the leading character of each word is uppercase. No inferences are made about language, so words like “as”, “to”, and “for” will still be capitalized.

use convert_case::{Case, Casing};
assert_eq!("My Variable Name", "My variable NAME".to_case(Case::Title))

Toggle

Toggle case strings are delimited by spaces. All characters are uppercase except for the leading character of each word, which is lowercase.

use convert_case::{Case, Casing};
assert_eq!("mY vARIABLE nAME", "My variable NAME".to_case(Case::Toggle))

Camel

Camel case strings are lowercase, but for every word except the first the first letter is capitalized.

use convert_case::{Case, Casing};
assert_eq!("myVariableName", "My variable NAME".to_case(Case::Camel))

Pascal

Pascal case strings are lowercase, but for every word the first letter is capitalized.

use convert_case::{Case, Casing};
assert_eq!("MyVariableName", "My variable NAME".to_case(Case::Pascal))

UpperCamel

Upper camel case is an alternative name for Pascal case.

Snake

Snake case strings are delimited by underscores _ and are all lowercase.

use convert_case::{Case, Casing};
assert_eq!("my_variable_name", "My variable NAME".to_case(Case::Snake))

UpperSnake

Upper snake case strings are delimited by underscores _ and are all uppercase.

use convert_case::{Case, Casing};
assert_eq!("MY_VARIABLE_NAME", "My variable NAME".to_case(Case::UpperSnake))

ScreamingSnake

Screaming snake case is an alternative name for upper snake case.

Kebab

Kebab case strings are delimited by hyphens - and are all lowercase.

use convert_case::{Case, Casing};
assert_eq!("my-variable-name", "My variable NAME".to_case(Case::Kebab))

Cobol

Cobol case strings are delimited by hyphens - and are all uppercase.

use convert_case::{Case, Casing};
assert_eq!("MY-VARIABLE-NAME", "My variable NAME".to_case(Case::Cobol))

Train

Train case strings are delimited by hyphens -. All characters are lowercase except for the leading character of each word.

use convert_case::{Case, Casing};
assert_eq!("My-Variable-Name", "My variable NAME".to_case(Case::Train))

Flat

Flat case strings are all lowercase, with no delimiter. Converting to this case is lossy. That is, word boundaries are lost.

use convert_case::{Case, Casing};
assert_eq!("myvariablename", "My variable NAME".to_case(Case::Flat))

UpperFlat

Upper flat case strings are all uppercase, with no delimiter. Converting to this case is lossy. That is, word boundaries are lost.

use convert_case::{Case, Casing};
assert_eq!("MYVARIABLENAME", "My variable NAME".to_case(Case::UpperFlat))

Alternating

Alternating case strings are delimited by spaces. Characters alternate between uppercase and lowercase.

use convert_case::{Case, Casing};
assert_eq!("mY vArIaBlE nAmE", "My variable NAME".to_case(Case::Alternating));

Implementations

impl Case

pub fn all_cases() -> Vec<Case>

Returns a vector with all case enum variants. This was created for use in the ccase binary.

Trait Implementations

impl Clone for Case

fn clone(&self) -> Case

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Case

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Case

fn eq(&self, other: &Case) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Case
