Function parse_style_animation 

pub fn parse_style_animation(
    input: &str,
) -> Result<StyleAnimation, StyleAnimationParseError<'_>>

Parse <name> <duration> [<delay>] [<timing>] [infinite | <count>].

The name is any non-keyword token; order is name-first (web animation shorthand accepts more permutations — the strict form keeps ambiguity out of native function names).

Errors

Returns StyleAnimationParseError when the value is empty, has no recognisable name, or its duration fails to parse.
