Implementations

impl Style

pub fn new(css: String, class: Option<String>) -> Result<Self, WasmCssError>

Construct a Style from a CSS string

• See style! for built-in formatting

• Generates random class name if one is not provided, returns WasmCssError if unable to locate Crypto when generating uuid for class name

• Filters out invalid CSS keys, use Style::new_checked if you would like to handle invalid CSS

---

Example Usage:

let style: Style = Style::new(
    "
        gap: 10rem;
        display: flex;
        flex-direction: column;
    ",
    None,
)?;

pub fn new_checked( css: String, class: Option<String>, ) -> Result<Self, WasmCssError>

Construct a Style from a CSS string with formatting, returning a WasmCssError of the invalid line if encountered during parsing

• See style_checked! for built-in formatting

• Generates random class name if one is not provided, returns WasmCssError if unable to locate Crypto when generating uuid for class name

---

Example Usage:

let style_result: Result<Style, WasmCssError> = Style::new_checked(
    "
        gap: 10rem;
        display: flex;
        flex-direction: column;
    ",
    None,
);

pub fn class(&self) -> &String

Returns this Styles class name

pub fn append(&mut self, source: &Style) -> Result<(), WasmCssError>

Append another Style to this one, overwriting any fields on self matching with source, or adding them if they did not previously exist, updating the Style

---

Example Usage:

let mut style_one = style!("color: red; font-size: 10rem;")?;

let style_two = style!("font-size: 30rem; background-color: red;")?;

style_one.append(&style_two)?;

// style_one.css: "color: red; font-size: 30rem; background-color: red;"

pub fn insert<V: Into<String>>( &mut self, key: &str, value: V, ) -> Result<(), WasmCssError>

Insert a new CSS line into the Style

• Skips invalid keys

---

Example Usage:

let mut style = style!("color: red; font-size: 10rem;")?;

style.insert("font-weight", "bold");

pub fn insert_checked<V: Into<String>>( &mut self, key: &str, value: V, ) -> Result<(), WasmCssError>

Insert a new CSS line into Style, retuning an error on invalid key

---

Example Usage:

let mut style = style!("color: red; font-size: 10rem;")?;

style.insert_checked("font-weight", "bold")?;

pub fn remove(&mut self, key: &str) -> Result<(), WasmCssError>

Remove a CSS line from Style

---

Example Usage:

let mut style = style!("color: red; font-size: 10rem;")?;

style.remove("color", "red")?;

pub fn insert_many<V: Into<String>>( &mut self, components: Vec<(&str, V)>, ) -> Result<(), WasmCssError>

Insert many CSS lines into the Style

Example Usage:

let mut style = style!("color: red; font-size: 10rem;")?;

style.insert_many(vec![
    ("font-weight", "bold"),
    ("background-color", "red")
])?;

pub fn insert_many_checked<V: Into<String>>( &mut self, components: Vec<(&str, V)>, ) -> Result<(), WasmCssError>

Insert many CSS lines into the Style, retuning an error on invalid key

---

Example Usage:
