Struct MetadataLoader 

pub struct MetadataLoader {}

MetadataLoader is a loader for reading persisted metadata files.

Examples

use lindera_dictionary::dictionary_loader::metadata::MetadataLoader;
use std::path::Path;

// Normal loading
let metadata = MetadataLoader::load(Path::new("/path/to/dictionary"))?;

// Memory-mapped loading (when mmap feature is enabled)
#[cfg(feature = "mmap")]
let metadata = MetadataLoader::load_mmap(Path::new("/path/to/dictionary"))?;

Implementations

impl MetadataLoader

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

Loads metadata file (metadata.json) from the specified directory.

Arguments

• input_dir - Path to the directory containing the metadata file

Returns

The loaded Metadata object, or an error

Errors

Returns an error if file reading fails or deserialization fails.

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

Loads metadata file using memory mapping.

This method is only available when the “mmap” feature is enabled. It’s useful for efficiently reading large files.

Arguments

• input_dir - Path to the directory containing the metadata file

Returns

The loaded Metadata object, or an error
