Struct FieldMut 

pub struct FieldMut<'a> { /* private fields */ }

Mutable typed view over a field-sized byte slice.

Produced by split_fields_mut (generated by zero_copy_layout!). Provides typed mutation without holding &mut to the whole struct.

Implementations

impl<'a> FieldMut<'a>

pub fn new(data: &'a mut [u8]) -> Self

Create a mutable field reference from a byte slice.

pub fn len(&self) -> usize

The byte length of this field.

pub fn is_empty(&self) -> bool
