Struct re_renderer::size::Size

#[repr(C)]
pub struct Size(pub f32);

Expand description

A size of something in either scene units or ui points.

Implementation:

If positive, this is in scene units.
If negative, this is in ui points.

type Bits = T

Self must have the same layout as the specified Bits except for the possible invalid bit patterns being checked during is_valid_bit_pattern.
