Struct FrameRules 

pub struct FrameRules { /* private fields */ }

Frame size rules

This is a special variant of SizeRules for frames. It is assumed that frames are not stretchy (i.e. that min-size equals ideal-size); additionally frame rules have a content offset and a minimum internal margin size.

Implementations

impl FrameRules

pub const ZERO: Self

pub const fn new(size: i32, inner: (u16, u16), outer: (u16, u16)) -> Self

Construct new FrameRules

All parameters use pairs (first, second) where first is the top/left component. Parameters inner and outer are inner and outer margin sizes respectively while size is the frame size.

If size > 0 then internal margins are the maximum of inner and content margin; generated rules have size content_size + size + inner_margin and outer margin outer.

If size ≤ 0 then the generated rules are simply content rules but with margins the maximum of inner and content margins; outer and size are ignored (other than to enable this mode).

pub const fn new_sym(size: i32, inner: u16, outer: u16) -> Self

Construct (symmetric on axis)

pub const fn size(&self) -> i32

Get the size of the frame itself (excluding margin)

pub fn surround(self, content: SizeRules) -> (SizeRules, i32, i32)

Generate rules for content surrounded by this frame

Returns the tuple (rules, offset, size):

• the generated rules
• the content offset within the allocated rect
• the size consumed by the frame and inner margins (thus the content’s size will be that allocated for this object minus this size value)
