Macro embedded_dictionary 

macro_rules! embedded_dictionary {
    ($dir:literal, $loader:ident) => { ... };
}

Generates the embedded-dictionary loader for a dictionary crate.

The dictionary data is baked into the binary with include_bytes!, reading from the LINDERA_WORKDIR directory populated by the crate’s build script.

The data is bound to statics rather than consts deliberately. A const body is encoded into the crate’s metadata, so a const here would put a copy of every dictionary byte into lib.rmeta at roughly 4x its size — several hundred megabytes per dictionary crate, re-read by every downstream crate. The data is private to load() below and never const-evaluated, so a static is all that is needed.

• $dir — the dictionary subdirectory inside LINDERA_WORKDIR (e.g. "/lindera-ipadic").
• $loader — the public loader struct name (e.g. EmbeddedIPADICLoader).

Example

lindera_dictionary::embedded_dictionary!("/lindera-ipadic", EmbeddedIPADICLoader);
