Struct CompiledQueryBuffer 

pub struct CompiledQueryBuffer { /* private fields */ }

Aligned buffer for compiled query data.

Allocated via Layout::from_size_align(len, BUFFER_ALIGN). Standard Box<[u8]> won’t work—it assumes 1-byte alignment and corrupts dealloc.

Implementations

impl CompiledQueryBuffer

pub fn allocate(len: usize) -> Self

Allocate a new buffer with 64-byte alignment.

pub unsafe fn from_external(ptr: *mut u8, len: usize) -> Self

Create a view into external memory (mmap’d or borrowed).

Safety

• ptr must be valid for reads of len bytes
• ptr must be aligned to BUFFER_ALIGN
• The backing memory must outlive the returned buffer

pub fn as_ptr(&self) -> *const u8

Returns a pointer to the buffer start.

pub fn as_mut_ptr(&mut self) -> *mut u8

Returns a mutable pointer to the buffer start.

pub fn len(&self) -> usize

Returns the buffer length in bytes.

pub fn is_empty(&self) -> bool

Returns true if the buffer is empty.

pub fn as_slice(&self) -> &[u8]

Returns the buffer as a byte slice.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Returns the buffer as a mutable byte slice.
