Struct Tolerance 

#[non_exhaustive]
pub struct Tolerance {
    pub channel: u8,
    pub pixels: u32,
}

How far a backend’s picture may be from the reference and still pass compare. Read from a plan file as (channel: 4); a key left out takes its default.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

channel: u8

The most a colour channel of a pixel may differ (0 to 255) before the pixel counts as different.

pixels: u32

How many pixels may differ.

Implementations

impl Tolerance

pub const fn new(channel: u8, pixels: u32) -> Self

Up to channel in each colour channel, and up to pixels pixels past that.

Trait Implementations

impl Clone for Tolerance

fn clone(&self) -> Tolerance

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

Formats the value using the given formatter.

impl Default for Tolerance

fn default() -> Self

2 in each channel (a GPU’s rounding), and no pixel past that.
