Struct AudioComponentInstantiationOptions

#[repr(transparent)]
pub struct AudioComponentInstantiationOptions(pub u32);

Available on crate feature AudioComponent only.

Options controlling component instantiation.

Most component instances are loaded into the calling process.

A version 3 audio unit, however, can be loaded into a separate extension service process, and this is the default behavior for these components. To be able to load one in-process requires that the developer package the audio unit in a bundle separate from the application extension, since an extension’s main binary cannot be dynamically loaded into another process.

A macOS host may request in-process loading of such audio units using kAudioComponentInstantiation_LoadInProcess.

kAudioComponentFlag_IsV3AudioUnit specifies whether an audio unit is implemented using API version 3.

These options are just requests to the implementation. It may fail and fall back to the default.

Attempt to load the component into a separate extension process.

Attempt to load the component into the current process. Only available on macOS.

pub const LoadOutOfProcess: Self

pub const LoadInProcess: Self

pub const LoadedRemotely: Self

impl AudioComponentInstantiationOptions

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

Get a flags value with all known bits set.

pub const fn bits(&self) -> u32

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: u32) -> Option<Self>

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: u32) -> Self

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u32) -> Self

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

pub fn insert(&mut self, other: Self)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: Self)

pub fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

pub const fn union(self, other: Self) -> Self

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl AudioComponentInstantiationOptions

pub const fn iter(&self) -> Iter<AudioComponentInstantiationOptions>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<AudioComponentInstantiationOptions>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
