Struct StructLayout 

pub struct StructLayout {
    pub struct_name: String,
    pub fields: Vec<(String, u64)>,
    pub total_size: u64,
    pub alignment: u64,
}

Describes the memory layout of a struct, used for field reordering analysis.

Fields

struct_name: String

The name of the struct.

fields: Vec<(String, u64)>

Ordered list of (field_name, field_size_bytes) pairs.

total_size: u64

Total size of the struct in bytes (including padding).

alignment: u64

Required alignment of the struct in bytes.

Implementations

impl StructLayout

pub fn is_cache_aligned(&self) -> bool

Returns true if the struct’s total size is a multiple of the cache line size (64 bytes).

pub fn padding_bytes(&self) -> u64

Returns the number of padding bytes in the struct.

pub fn cache_lines_used(&self) -> u64

Returns the number of cache lines the struct spans.

Trait Implementations

impl Clone for StructLayout

fn clone(&self) -> StructLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StructLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for StructLayout

fn eq(&self, other: &StructLayout) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
