LazyEntries

mecab_ko::dict::lazy_entries

Struct LazyEntries 

Source 
pub struct LazyEntries { /* private fields */ }
Expand description

지연 로딩 엔트리 저장소

엔트리를 필요할 때만 디스크에서 읽어옵니다. 자주 사용되는 엔트리는 LRU 캐시에 저장됩니다.

Implementations§

Source§

impl LazyEntries

Source

pub fn from_file<P>(path: P) -> Result<LazyEntries, DictError>
where P: AsRef<Path>,

entries.bin v2 파일에서 로드

§Errors
  • 파일 형식이 잘못된 경우
  • 파일 읽기 실패한 경우
§Safety

Uses memory-mapped I/O which requires unsafe. The safety is ensured by memmap2 crate’s implementation.

Source

pub const fn len(&self) -> usize

엔트리 수 반환

Source

pub const fn is_empty(&self) -> bool

비어있는지 확인

Source

pub fn cached_count(&self) -> usize

캐시된 엔트리 수 반환

Source

pub fn set_cache_size(&self, size: usize)

캐시 크기 설정

Source

pub fn clear_cache(&self)

캐시 초기화

Source

pub fn get(&self, index: u32) -> Result<Arc<DictEntry>, DictError>

인덱스로 엔트리 로드

캐시에 있으면 캐시에서 반환, 없으면 디스크에서 읽어 캐시에 저장

§Errors
  • 인덱스가 범위를 벗어난 경우
  • 엔트리 읽기 실패한 경우
Source

pub fn get_entries_at( &self, first_index: u32, surface: &str, ) -> Result<Vec<Arc<DictEntry>>, DictError>

인덱스에서 시작하여 같은 surface를 가진 연속된 엔트리 반환

§Errors
  • 인덱스가 범위를 벗어난 경우
  • 엔트리 읽기 실패한 경우
Source

pub fn load_all(&self) -> Result<Vec<DictEntry>, DictError>

모든 엔트리를 Vec으로 로드 (마이그레이션/변환용)

주의: 대용량 사전에서는 메모리를 많이 사용합니다.

§Errors
  • 엔트리 읽기 실패한 경우
Source

pub fn save_entries<P>(entries: &[DictEntry], path: P) -> Result<(), DictError>
where P: AsRef<Path>,

DictEntry 벡터를 entries.bin v2로 저장

§Errors
  • 파일 쓰기 실패 시 에러
