# parquet-full API reference

> The `parquet_full` package, from parquet-full 0.1.8, as published on mojoshelf (commit c15f51aee06c), by `mojo doc` from Mojo 1.2.0.

The codec set that includes ZSTD, LZ4 and BROTLI.

`zstd.mojo`, `lz4.mojo` and `brotli.mojo` dlopen libzstd / liblz4 / libbrotli,
so a consumer that wants these has to have those tins installed *and* on the
include path:

```console
mojo build … -I ../zstd.mojo/src -I ../lz4.mojo/src -I ../brotli.mojo/src
```

Everything `DefaultCodecs` handles is handled here too. Between the two sets
that is every codec in the Parquet spec.

## Structs

### `AllCodecs`

```mojo
struct AllCodecs
```

`UNCOMPRESSED`, `SNAPPY`, `GZIP`, `ZSTD`, `BROTLI`, `LZ4_RAW` and legacy `LZ4` — every codec the Parquet spec defines.

Implements: `CodecSet`, `Movable`

#### `supports`

```mojo
def supports(codec: Int32) -> Bool
```

#### `decompress`

```mojo
def decompress[page_origin: ImmOrigin, scratch_origin: MutOrigin](codec: Int32, data: Span[UInt8, page_origin], uncompressed_size: Int, ref[scratch_origin] scratch: List[UInt8]) -> Span[UInt8, origin_of(page_origin, scratch_origin)].Immutable
```

#### `compress`

```mojo
def compress(codec: Int32, data: Span[UInt8]) -> List[UInt8]
```
