Struct rocket_db_pools::figment::value::UncasedStr
[−]#[repr(transparent)]pub struct UncasedStr(_);
Expand description
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
impl UncasedStr
pub const fn new(string: &str) -> &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
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
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
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
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"));
pub fn into_uncased(self: Box<UncasedStr, Global>) -> Uncased<'static>
Available on crate feature alloc
only.
pub fn into_uncased(self: Box<UncasedStr, Global>) -> Uncased<'static>
alloc
only.Converts a Box<UncasedStr>
into an Uncased
without copying or
allocating.
Example
use uncased::Uncased;
let uncased = Uncased::new("Hello!");
let boxed = uncased.clone().into_boxed_uncased();
assert_eq!(boxed.into_uncased(), uncased);
