Enum SwitchQuant 

pub enum SwitchQuant {
    PatternEnd,
    Bar,
    Beat,
    Immediate,
}

When a queued pattern change takes effect.

Every one of these is a function of the song position, so the point a switch will happen is known the moment it is queued — which is what lets the UI count down to it rather than saying “soon”.

Variants

PatternEnd

At the end of the pattern currently playing. The default, because it is the one that keeps the part in phase with itself.

Bar

At the next bar line (4/4).

Beat

At the next beat.

Immediate

At the start of the next callback.

Implementations

impl SwitchQuant

pub const ALL: [SwitchQuant; 4]

pub const fn label(self) -> &'static str

pub const fn index(self) -> u8

pub fn from_index(index: u8) -> Self

pub fn stepped(self, delta: i32) -> Self

pub fn boundary(self, now: i64, pattern_ticks: i64) -> i64

The first tick at or after now where a switch under this quantization may happen.

pattern_ticks is the length of the pattern that is playing — the grid PatternEnd counts in. A tick that is already on the grid is itself the answer, so a switch queued exactly on a bar line takes effect on that bar line rather than the next.
