Enum ParsedLength 

pub enum ParsedLength {
    Px(f32),
    Percent(f32),
    Em(f32),
    Rem(f32),
    Vw(f32),
    Vh(f32),
    Fr(f32),
    Auto,
}

Internal parsed representation. Once parsed we know which unit it is.

Implementations

impl ParsedLength

pub fn resolve(&self, ctx: &LengthContext) -> Option<f32>

Resolve to absolute pixels. Returns None for Auto / Fr (caller decides).

pub fn is_relative(&self) -> bool

True for units whose absolute pixel value depends on a LengthContext (%, em, rem, vw, vh) — i.e. everything Length::px / LengthPercentage::px cannot resolve on their own and silently (issue #125 §2) or loudly (post-fix) fall back to 0.0 for. Px needs no context; Auto/Fr are not scalar lengths at all (the caller decides what they mean) so they are not “relative” in this sense.
