Struct uncased::UncasedStr

#[repr(transparent)]
pub struct UncasedStr(_);

A cost-free reference to an uncased (case-insensitive, case-preserving) ASCII string.

This is typically created from an &str as follows:

use uncased::UncasedStr;

let ascii_ref: &UncasedStr = "Hello, world!".into();

Implementations

impl UncasedStr

pub const fn new(string: &str) -> &UncasedStr

Cost-free conversion from an &str reference to an UncasedStr.

This is a const fn on Rust 1.56+.

Example

use uncased::UncasedStr;

let uncased_str = UncasedStr::new("Hello!");
assert_eq!(uncased_str, "hello!");
assert_eq!(uncased_str, "Hello!");
assert_eq!(uncased_str, "HeLLo!");

pub fn as_str(&self) -> &str

Returns self as an &str.

Example

use uncased::UncasedStr;

let uncased_str = UncasedStr::new("Hello!");
assert_eq!(uncased_str.as_str(), "Hello!");
assert_ne!(uncased_str.as_str(), "hELLo!");

pub fn len(&self) -> usize

Returns the length, in bytes, of self.

Example

use uncased::UncasedStr;

let uncased_str = UncasedStr::new("Hello!");
assert_eq!(uncased_str.len(), 6);

pub fn is_empty(&self) -> bool

Returns true if self has a length of zero bytes.

Examples

use uncased::UncasedStr;

let s = UncasedStr::new("");
assert!(s.is_empty());

let s = UncasedStr::new("not empty");
assert!(!s.is_empty());

pub fn starts_with(&self, string: &str) -> bool

Returns true if self starts with any casing of the string string; otherwise, returns false.

Example

use uncased::UncasedStr;

let uncased_str = UncasedStr::new("MoOO");
assert!(uncased_str.starts_with("moo"));
assert!(uncased_str.starts_with("MOO"));
assert!(uncased_str.starts_with("MOOO"));
assert!(!uncased_str.starts_with("boo"));

let uncased_str = UncasedStr::new("Bèe");
assert!(!uncased_str.starts_with("Be"));
assert!(uncased_str.starts_with("Bè"));
assert!(uncased_str.starts_with("Bè"));
assert!(uncased_str.starts_with("bèe"));
assert!(uncased_str.starts_with("BèE"));
