Struct style_traits::values::SequenceWriter

pub struct SequenceWriter<'a, 'b: 'a, W: 'b> {
    inner: &'a mut CssWriter<'b, W>,
    separator: &'static str,
}

Convenience wrapper to serialise CSS values separated by a given string.

Fields

inner: &'a mut CssWriter<'b, W>

separator: &'static str

Implementations

impl<'a, 'b, W> SequenceWriter<'a, 'b, W>

where W: Write + 'b,

pub fn new(inner: &'a mut CssWriter<'b, W>, separator: &'static str) -> Self

Create a new sequence writer.

pub fn write_item<F>(&mut self, f: F) -> Result

where F: FnOnce(&mut CssWriter<'b, W>) -> Result,

Serialize the CSS Value with the specific serialization function.

pub fn item<T>(&mut self, item: &T) -> Result

where T: ToCss,

Serialises a CSS value, writing any separator as necessary.

The separator is never written before any item produces any output, and is written in subsequent calls only if the item produces some output on its own again. This lets us handle Option<T> fields by just not printing anything on None.

pub fn raw_item(&mut self, item: &str) -> Result

Writes a string as-is (i.e. not escaped or wrapped in quotes) with any separator as necessary.
