Struct alchemy_styles::StyleKey

pub struct StyleKey(_);

A valid CSS class.

A CSS class is a non-empty string that starts with an alphanumeric character and is followed by any number of alphanumeric characters and the _, - and . characters.

Methods

impl StyleKey

pub fn try_new<S: Into<String>>(id: S) -> Result<Self, &'static str>

Construct a new styles list from a string.

Returns Err if the provided string is invalid.

pub fn new<S: Into<String>>(id: S) -> Self

Construct a new class name from a string.

Panics if the provided string is invalid.

Methods from Deref<Target = String>

pub fn as_str(&self) -> &str

Extracts a string slice containing the entire String.

Examples

Basic usage:

let s = String::from("foo");

assert_eq!("foo", s.as_str());

pub fn capacity(&self) -> usize

Returns this String's capacity, in bytes.

Examples

Basic usage:

let s = String::with_capacity(10);

assert!(s.capacity() >= 10);

pub fn as_bytes(&self) -> &[u8]

Returns a byte slice of this String's contents.

The inverse of this method is from_utf8.

Examples

Basic usage:

let s = String::from("hello");

assert_eq!(&[104, 101, 108, 108, 111], s.as_bytes());

pub fn len(&self) -> usize

Returns the length of this String, in bytes.

Examples

Basic usage:

let a = String::from("foo");

assert_eq!(a.len(), 3);

pub fn is_empty(&self) -> bool

Returns true if this String has a length of zero, and false otherwise.

Examples

Basic usage:

let mut v = String::new();
assert!(v.is_empty());

v.push('a');
assert!(!v.is_empty());
