Enum AuxPresentMode 

pub enum AuxPresentMode {
    NonBlocking(&'static str),
    Fifo,
}

The present mode a secondary surface ended up with, so the shell can record which arm ran (ADR-0071 reporting: a frame-time measurement that does not name its present mode cannot be compared with another machine’s).

Variants

NonBlocking(&'static str)

A non-blocking mode was offered and taken: the console’s present does not block on its own display’s vblank.

That is a property of this surface’s present, not a guarantee about the output’s cadence — the two presents still run on one thread, and what the second costs the first is a measurement rather than a deduction. Measured at Plan 0147 Phase 4 on an integrated Radeon: at the 165 Hz vsync cap, 14,797 console presents cost the output 0.0 fps.

Fifo

Only Fifo was offered. The console presents in lockstep with its own display, which is the configuration where a slower second monitor can be felt on the output.

Implementations

impl AuxPresentMode

pub fn as_str(self) -> &'static str

The mode’s name, for the diagnostic log line.

Trait Implementations

impl Clone for AuxPresentMode

fn clone(&self) -> AuxPresentMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuxPresentMode

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

Formats the value using the given formatter.

impl PartialEq for AuxPresentMode

fn eq(&self, other: &AuxPresentMode) -> 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.
