Struct PrefixDictionaryLoader 

pub struct PrefixDictionaryLoader {}

Loader for prefix dictionary data from disk files.

Implementations

impl PrefixDictionaryLoader

pub fn load(input_dir: &Path) -> LinderaResult<PrefixDictionary>

Load prefix dictionary from files in the specified directory.

Reads dict.da, dict.vals, dict.wordsidx, and dict.words files and constructs a PrefixDictionary.

Arguments

• input_dir - Path to the directory containing dictionary files.

Returns

A PrefixDictionary loaded from the files.

pub fn load_mmap(input_dir: &Path) -> LinderaResult<PrefixDictionary>

Load prefix dictionary using memory-mapped files.

Note: only vals_data/words_idx_data/words_data end up genuinely mmap-backed (read lazily at lookup time via Data::Map). da_data is still eagerly copied into an owned DoubleArrayAhoCorasick by PrefixDictionary::load — daachorse has no zero-copy deserialization API — so mmap only avoids the initial file-read syscall/allocation for that component, not runtime lazy paging. mmap’d bytes are passed with DaTrust::Untrusted, the same as a plain read: they can be corrupted or tampered with just as easily as a regular file.

Arguments

• input_dir - Path to the directory containing dictionary files.

Returns

A PrefixDictionary loaded via memory mapping.
