Struct CStructLayout 

pub struct CStructLayout {
    pub name: String,
    pub fields: Vec<(String, usize, usize)>,
}

A C-ABI struct layout: a list of fields with names, sizes, and alignments.

Fields

name: String

Name of the struct.

fields: Vec<(String, usize, usize)>

Fields: (name, size, alignment).

Implementations

impl CStructLayout

pub fn new(name: impl Into<String>) -> Self

Create a new (empty) CStructLayout.

pub fn add_field( self, name: impl Into<String>, size: usize, align: usize, ) -> Self

Add a field with the given name, size, and alignment.

pub fn field_offset(&self, idx: usize) -> usize

Compute the byte offset of the n-th field following C ABI rules.

pub fn total_size(&self) -> usize

Total size of the struct including trailing padding.

pub fn describe(&self) -> String

Describe this struct layout.
