Struct MemoryLayout 

pub struct MemoryLayout {
    pub type_name: String,
    pub size: usize,
    pub align: usize,
}

A memory layout descriptor for a Rust/C type.

Tracks size, alignment, and stride (size rounded up to alignment).

Fields

type_name: String

Name of the type.

size: usize

Size of the type in bytes.

align: usize

Alignment of the type in bytes.

Implementations

impl MemoryLayout

pub fn new(type_name: impl Into<String>, size: usize, align: usize) -> Self

Create a new MemoryLayout.

pub fn stride(&self) -> usize

The stride: size rounded up to the alignment boundary.

pub fn is_valid(&self) -> bool

Check whether this layout is valid (align is a power of two, size ≤ stride).

pub fn align_offset(&self, offset: usize) -> usize

Compute the offset needed to align offset to this type’s alignment.

pub fn describe(&self) -> String

Return a description of this layout.
