}

A height field with compressed storage.

Maps to C’s b3HeightFieldData + trailing blob. Offsets and byte_count match C so HeightFieldData::to_bytes reproduces the contiguous layout used by b3Hash.

Implementations

impl HeightFieldData

pub fn from_bytes(bytes: &[u8]) -> Option<HeightFieldData>

Restore from a contiguous blob. (inverse of [to_bytes])

pub fn to_bytes(&self) -> Vec<u8>

Serialize to the C contiguous trailing-blob layout (for hash parity).

pub fn to_bytes_with_hash(&self, hash: u32) -> Vec<u8>

Like [to_bytes], but with an explicit hash field (use 0 when computing the hash).

Trait Implementations

impl Clone for HeightFieldData

fn clone(&self) -> HeightFieldData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeightFieldData

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

Formats the value using the given formatter.

impl Default for HeightFieldData

fn default() -> Self

Returns the “default value” for a type.
