# dec

Library to allow decoding of more complex values

## Functions

### `hex::dec::demangle`

Demangles a mangled name into a human readable name

* `mangled_name`: The mangled name
* `return`: The demangled name

```rust
fn demangle( mangled_name);
```

### `hex::dec::zlib_decompress`

Decompresses the bytes of a pattern into a section using the zlib algorithm

* `pattern`: The pattern whose bytes should be decompressed
* `section`: The section to decompress the data into
* `window_size`: The window size passed to zlib
* `return`: A value representing either the number of bytes decompressed or an error code from zlib

```rust
fn zlib_decompress( pattern, std::mem::Section section,  window_size);
```

### `hex::dec::bzip_decompress`

Decompresses the bytes of a pattern into a section using the bzip algorithm

* `pattern`: The pattern whose bytes should be decompressed
* `section`: The section to decompress the data into
* `return`: true if successful, false otherwise

```rust
fn bzip_decompress( pattern, std::mem::Section section);
```

### `hex::dec::lzma_decompress`

Decompresses the bytes of a pattern into a section using the LZMA algorithm

* `pattern`: The pattern whose bytes should be decompressed
* `section`: The section to decompress the data into
* `return`: true if successful, false otherwise

```rust
fn lzma_decompress( pattern, std::mem::Section section);
```

### `hex::dec::zstd_decompress`

Decompresses the bytes of a pattern into a section using the zstd algorithm

* `pattern`: The pattern whose bytes should be decompressed
* `section`: The section to decompress the data into
* `return`: true if successful, false otherwise

```rust
fn zstd_decompress( pattern, std::mem::Section section);
```

### `hex::dec::lz4_decompress`

Decompresses the bytes of a pattern into a section using the lz4 algorithm

* `pattern`: The pattern whose bytes should be decompressed
* `section`: The section to decompress the data into
* `frame`: Whether the data is framed or not
* `return`: true if successful, false otherwise

```rust
fn lz4_decompress( pattern, std::mem::Section section,  frame);
```
