Struct PulseDrumMachine 

pub struct PulseDrumMachine { /* private fields */ }

Convenience builder for common 808 drum-machine patterns.

Implementations

impl PulseDrumMachine

pub fn new(kit: &str) -> PulseResult<Self>

Creates a drum-machine builder for a kit name.

Errors

Returns an error for unsupported kit names.

pub fn steps(self, steps: usize) -> PulseResult<Self>

Sets the backing grid step count.

Errors

Returns an error when steps is zero.

pub fn step_duration(self, duration: f32) -> PulseResult<Self>

Sets the backing grid step duration in beats.

Errors

Returns an error when duration is invalid.

pub fn kick(self, pattern: Vec<usize>) -> PulseResult<Self>

Adds 808 kick hits.

Errors

Returns an error if the mapped drum alias cannot be resolved.

pub fn snare(self, pattern: Vec<usize>) -> PulseResult<Self>

Adds 808 snare hits.

Errors

Returns an error if the mapped drum alias cannot be resolved.

pub fn hihat(self, pattern: Vec<usize>) -> PulseResult<Self>

Adds closed 808 hi-hat hits.

Errors

Returns an error if the mapped drum alias cannot be resolved.

pub fn open_hihat(self, pattern: Vec<usize>) -> PulseResult<Self>

Adds open 808 hi-hat hits.

Errors

Returns an error if the mapped drum alias cannot be resolved.

pub fn clap(self, pattern: Vec<usize>) -> PulseResult<Self>

Adds 808 clap hits.

Errors

Returns an error if the mapped drum alias cannot be resolved.

pub fn grid(self) -> PulseDrumGrid

Finishes the builder and returns its drum grid.

pub fn kit(&self) -> DrumKit

Returns the selected kit.

Trait Implementations

impl Clone for PulseDrumMachine

fn clone(&self) -> PulseDrumMachine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PulseDrumMachine

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

Formats the value using the given formatter.

impl PartialEq for PulseDrumMachine

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

impl StructuralPartialEq for PulseDrumMachine

impl UserData for PulseDrumMachine

fn add_methods<M: UserDataMethods<Self>>(methods: &mut M)

Adds custom methods and operators specific to this userdata.

fn add_fields<F>(fields: &mut F)

where F: UserDataFields<Self>,

Adds custom fields specific to this userdata.

fn register(registry: &mut UserDataRegistry<Self>)

Registers this type for use in Lua.
