Struct FrameHasher 

pub struct FrameHasher { /* private fields */ }

Hashes frame content without the status bar.

Implementations

impl FrameHasher

pub const DEFAULT_STATUS_BAR_FRACTION: f32 = 0.06

The share of the screen height taken for the status bar when nothing better is known: 6 %, 144 of 2400 rows, which S7 found covers the Pixel 8 profile’s status bar.

pub fn new(status_bar_fraction: f32) -> Self

A hasher that leaves out the top status_bar_fraction of every frame, clamped to 0 through 1; NaN leaves nothing out.

pub fn status_bar_rows(&self, height: u32) -> u32

Rows at the top of a frame height rows high that the hash leaves out.

pub fn key(&self, frame: &Frame) -> FrameKey

The key of frame.
