Struct RecHeader 

pub struct RecHeader {
    pub magic: u32,
    pub version_major: u16,
    pub version_minor: u16,
    pub length_scale: f32,
    pub pointer_width: u8,
    pub big_endian: u8,

}

File header, fixed 32 bytes, little-endian. (b2RecHeader)

Fields

magic: u32

‘B2RC’ = 0x43523242

version_major: u16

version_minor: u16

length_scale: f32

The world length scale

pointer_width: u8

sizeof(void*) in C, gates POD-def memcpy; always 8 here

big_endian: u8

0 on all supported targets

validation_enabled: u8

1 if built with validation, only for diagnostics on a layout mismatch

snapshot_size: u64

bytes of snapshot blob after the header

Implementations

impl RecHeader

pub const SIZE: usize = 32

pub fn write(&self, buf: &mut Vec<u8>)

Serialize in the exact C struct layout (little-endian, with the reserved fields zeroed).

pub fn read(data: &[u8]) -> Option<RecHeader>

Parse a 32-byte header. Returns None if the data is too short.
