Struct HelpcodeKeymap 

pub struct HelpcodeKeymap { /* private fields */ }

A helpcode table: the code letters (one or two, lowercase) of each character, which the session uses to filter and order candidates and to annotate them. Read one from a resource directory with load_helpcode_keymap, from a file’s bytes with HelpcodeKeymap::from_table_bytes, or build one with HelpcodeKeymap::from_codes; a session takes it through SessionOptions::helpcode_table or Session::set_helpcode_table.

Implementations

impl HelpcodeKeymap

pub fn from_codes(codes: HashMap<String, String>) -> Self

A table from character to code letters as given; the caller has already applied the file rules of load_helpcode_keymap.

pub fn from_table_bytes(bytes: &[u8]) -> Option<Self>

从码表文件的字节解析，规则与 load_helpcode_keymap 读文件时相同；给没有文件系统的宿主（网页引擎）用。超过 1 MiB 的表返回 None，与读文件时的上限一致。

pub fn code(&self, character: &str) -> Option<&str>

The code letters of one character, lowercase.
