Struct Differences 

pub struct Differences {
    pub count: usize,
    pub inside: usize,
    pub rows: Vec<(u32, Vec<(u32, u32)>)>,
    pub kept_base: usize,
    pub render_base: usize,
    pub first: Option<(u32, u32, [u8; 4], [u8; 4])>,
    pub bounds: Option<(u32, u32, u32, u32)>,
}

How a frame repainted in part differed from a full render of it.

Fields

count: usize

How many pixels differ.

inside: usize

How many of them lie more than eight pixels inside Self::bounds: 0 says the difference is the outline of a rectangle, not its fill.

rows: Vec<(u32, Vec<(u32, u32)>)>

For each row that differs, up to [DIFF_ROWS] of them, the runs of columns that differ, up to [DIFF_RUNS] a row.

kept_base: usize

How many of them are the colour the target was cleared with in the frame repainted in part: geometry missing from what the target shows.

render_base: usize

How many of them are that colour in the full render: geometry the check’s own render dropped, which names no stale frame.

first: Option<(u32, u32, [u8; 4], [u8; 4])>

The first pixel that differs beyond the ±1 two renders of one frame may differ by: where it is, then its colour in the frame repainted in part and in the full render.

bounds: Option<(u32, u32, u32, u32)>

The left, top, right and bottom of the pixels that differ, the far edges exclusive, or None where none do.

Trait Implementations

impl Clone for Differences

fn clone(&self) -> Differences

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Differences

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Differences

fn eq(&self, other: &Differences) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
