Struct RawSequence 

pub struct RawSequence { /* private fields */ }

A sequence that stores heterogeneous values with proper alignment.

The RawSequence provides a memory-efficient way to store heterogeneous values while maintaining proper alignment requirements for each type. It uses an internal buffer that aligns values according to their type’s requirements, up to a maximum alignment of 4096 bytes.

Implementations

impl RawSequence

pub fn new() -> RawSequence

Creates a new empty RawSequence. The sequence is initialized with a 4096-byte aligned buffer.

pub fn push<T>(&mut self, value: T)

Pushes a value onto the sequence.

The value is stored at an address that satisfies its alignment requirements. Automatically grows the internal buffer if needed.

Panics

Panics if the type’s alignment requirement exceeds 4096 bytes.

pub unsafe fn drop_in_place<T>(&mut self, p: usize) -> usize

Drops a value in-place at the specified position.

Safety

• The position must point to a valid value of type T
• The caller must ensure that the value is actually of type T

Returns the position immediately after the dropped value.

pub unsafe fn next<T>(&self, p: usize) -> (&T, usize)

Retrieves a reference to the next value at the specified position.

Safety

• The position must point to a valid value of type T
• The caller must ensure that the value is actually of type T

Returns a tuple containing:

• A reference to the value
• The position immediately after the value

pub fn len(&self) -> usize

Returns the number of bytes in the RawSequence, also referred to as its ‘length’.

pub fn is_empty(&self) -> bool

Returns true if the RawSequence has no elements.

Trait Implementations

impl Default for RawSequence

fn default() -> RawSequence

Returns the “default value” for a type.
