Struct fastanvil::RegionBuffer

pub struct RegionBuffer<S: Seek + Read> { /* fields omitted */ }

A Minecraft Region. Allows access to chunk data, handling decompression.

Implementations

impl<S: Seek + Read> RegionBuffer<S>

pub fn new(data: S) -> Self

pub fn chunk_location(&self, x: usize, z: usize) -> Result<ChunkLocation>

Return the (region-relative) Chunk location (x, z)

pub fn load_chunk(&self, x: usize, z: usize) -> Result<Vec<u8>>

Return the raw, uncompressed NBT data for a chunk at the (region-relative) Chunk location (x, z). Region’s hold 32 by 32 chunks.

Can be further processed with stream::Parser or even with Blob::from_reader() of hematite_nbt.

pub fn for_each_chunk(
    &mut self,
    f: impl FnMut(usize, usize, &Vec<u8>)
) -> Result<()>

Call function with each uncompressed, non-empty chunk, calls f(x, z, data).

Trait Implementations

impl<S: Seek + Read + Send + Sync, C: Chunk + DeserializeOwned> Region<C> for RegionBuffer<S>

fn chunk(&self, x: CCoord, z: CCoord) -> Option<C>

Load the chunk at the given chunk coordinates, ie 0..32 for x and z. Implmentations do not need to be concerned with caching chunks they have loaded, this will be handled by the types using the region.
