Struct VtkBinaryWriter 

pub struct VtkBinaryWriter;

Utilities for writing numeric data in little-endian binary format.

Implementations

impl VtkBinaryWriter

pub fn encode_f64_le(values: &[f64]) -> Vec<u8>

Encode a slice of f64 values as little-endian bytes.

pub fn encode_i64_le(values: &[i64]) -> Vec<u8>

Encode a slice of i64 values as little-endian bytes.

pub fn encode_u8(values: &[u8]) -> Vec<u8>

Encode a slice of u8 values (pass-through).

pub fn base64_encode(data: &[u8]) -> String

Base64-encode a byte slice (same algorithm as XmlVtuWriter::encode_base64).

pub fn binary_data_array_xml( name: &str, n_components: usize, values: &[f64], ) -> String

Build a binary-format DataArray XML element for float64 data.

The data is base64-encoded with a 4-byte little-endian length prefix.
