Struct DictionarySizes 

pub struct DictionarySizes {
    pub content: usize,
    pub serialized: usize,
}

The sizes of a dictionary handed to Matcher::set_dictionary_size_hint.

Upstream picks the CDict’s cParams tier from the size of the serialized dictionary buffer (ZSTD_createCDict(dictBuffer, dictSize, level), header and entropy tables included), while the dictionary tables and the attach cutoffs are sized from the content that is actually indexed.

Examples

use structured_zstd::encoding::DictionarySizes;
let sizes = DictionarySizes::raw_content(4096);
assert_eq!(sizes.serialized, sizes.content);

Fields

content: usize

Bytes of dictionary content the matcher indexes.

serialized: usize

Bytes of the serialized dictionary (the CDict cParams tier key); equal to content for a raw-content dictionary.

Implementations

impl DictionarySizes

pub const fn raw_content(len: usize) -> Self
