Struct kas::layout::FrameRules

pub struct FrameRules { /* fields omitted */ }

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 fn new(
    first: i32,
    second: i32,
    inner_margin: i32,
    outer_margins: (u16, u16)
) -> FrameRules

Construct

• first: size of left or top edge
• second: size of right or bottom edge
• inner_margin: minimum size of inner margins
• outer_margins: size of (left, right) or (top, bottom) outer margins

pub fn new_sym(size: i32, inner_margin: i32, outer_margin: u16) -> FrameRules

Construct (symmetric on axis)

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

Generate rules for content surrounded by this frame

It is assumed that the content’s margins apply inside this frame, and that the margin is at least as large as self’s inner_margin.

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)

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

Variant: frame surrounds content

The content’s margin is reduced by the size of the frame, with any residual margin applying outside the frame (using the max of the frame’s own margin and the residual). In other respects, this is the same as FrameRules::surround_with_margin.
