Struct Dictionary 

pub struct Dictionary { /* private fields */ }

A parsed Zstandard dictionary, ready to seed decompression.

Build one with Dictionary::new (which auto-detects the formatted and raw-content cases) or Dictionary::raw_content. Pass it to DecodeOptions::dictionary.

Implementations

impl Dictionary

pub fn new(bytes: &[u8]) -> Result<Self, Error>

Parse a dictionary buffer.

A buffer that begins with the ZDICT magic number is parsed as a formatted dictionary; anything else is treated as raw content, matching the C library’s ZSTD_isFrameMagic/raw-content fallback. A buffer that begins with the magic but is malformed yields Error::DictionaryCorrupted.

pub fn raw_content(content: &[u8]) -> Self

Treat content as a raw-content dictionary: window history with the default repeat offsets and no precomputed entropy tables. The dictionary ID is zero.

pub fn id(&self) -> u32

The dictionary ID, or zero for a raw-content dictionary (or a formatted dictionary that declares ID zero).
