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.

Frames have an inner margin, whose size is the maximum of inner and content margins. Additionally, frames have an external margin of size outer.

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)
