Struct RawBufferScratch 

pub struct RawBufferScratch {
    pub input_slices: Vec<&'static [f32]>,
    pub output_slices: Vec<&'static mut [f32]>,
}

Scratch space for AudioBuffer::from_raw_ptrs.

Callers allocate this on the stack and pass it to from_raw_ptrs. The buffer borrows the slices stored here, so this struct must outlive the returned AudioBuffer.

Fields

input_slices: Vec<&'static [f32]>

output_slices: Vec<&'static mut [f32]>

Implementations

impl RawBufferScratch

pub unsafe fn build<'a>( &'a mut self, inputs: *const *const f32, outputs: *mut *mut f32, num_in: u32, num_out: u32, num_frames: u32, ) -> AudioBuffer<'a>

Build an AudioBuffer from raw C pointers.

This is the common FFI pattern used by VST3, VST2, AU, and AAX wrappers. It:

1. Converts raw *const f32 / *mut f32 channel pointers to slices
2. Copies input channels to output channels (in-place effect processing)
3. Returns an AudioBuffer borrowing the scratch slices

Safety

• inputs must point to num_in valid *const f32 pointers, each pointing to num_frames samples.
• outputs must point to num_out valid *mut f32 pointers, each pointing to num_frames samples.
• The pointed-to memory must remain valid for the lifetime of the returned AudioBuffer.

Trait Implementations

impl Default for RawBufferScratch

fn default() -> Self

Returns the “default value” for a type.
