Struct FpZipHeader 

pub struct FpZipHeader {
    pub data_type: FpZipType,
    pub prec: u32,
    pub nx: u32,
    pub ny: u32,
    pub nz: u32,
    pub nf: u32,
}

Metadata header for FpZip compressed data.

Contains the data type, bit precision, and array dimensions. The header is encoded through the arithmetic range coder as part of the compressed stream (not as raw bytes), matching the C++ fpzip wire format.

Fields

data_type: FpZipType

The floating-point type (float or double).

prec: u32

Bit precision. Full precision for the type means lossless (32 for float, 64 for double).

nx: u32

X dimension size.

ny: u32

Y dimension size.

nz: u32

Z dimension size.

nf: u32

Number of fields (4th dimension).

Implementations

impl FpZipHeader

pub fn new(data_type: FpZipType, nx: u32, ny: u32, nz: u32, nf: u32) -> Self

pub fn total_elements(&self) -> u64

Total number of elements.

pub fn write_to_encoder(&self, enc: &mut RangeEncoder)

Writes the header through the range encoder (C++ compatible format).

pub fn read_from_decoder(dec: &mut RangeDecoder<'_>) -> Result<Self>

Reads the header through the range decoder (C++ compatible format).

Trait Implementations

impl Clone for FpZipHeader

fn clone(&self) -> FpZipHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FpZipHeader

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

Formats the value using the given formatter.

impl PartialEq for FpZipHeader

fn eq(&self, other: &FpZipHeader) -> 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.
