Struct fuchsia_zircon_types::PadByte

#[repr(C)]
pub struct PadByte(/* private fields */);

A byte used only to control memory alignment. All padding bytes are considered equal regardless of their content.

Note that the kernel C/C++ struct definitions use explicit padding fields to ensure no implicit padding is added. This is important for security since implicit padding bytes are not always safely initialized. These explicit padding fields are mirrored in the Rust struct definitions to minimize the opportunities for mistakes and inconsistencies.
