Struct LanguageDictionary 

pub struct LanguageDictionary { /* private fields */ }

An open language dictionary whose format version has been checked.

Implementations

impl LanguageDictionary

pub fn metadata(&self, name: &str) -> Result<Option<String>>

The metadata value stored under name.

pub fn lookup(&self, key: &str, limit: usize) -> Result<Vec<LanguageEntry>>

The entries stored under exactly key, heaviest first and by text within a weight, at most limit.

pub fn lookup_into( &self, key: &str, limit: usize, result: &mut Vec<LanguageEntry>, ) -> Result<()>

将精确键的查询结果写入已有缓冲，保留其中字符串的容量。

pub fn has_syllable(&self, syllable: &str) -> Result<bool>

Whether syllable is in the scheme’s syllable inventory.

pub fn syllables(&self) -> Result<Vec<String>>

The whole syllable inventory, for a scheme that segments typed letters against it in memory.

pub fn lookup_completions( &self, prefix: &str, limit: usize, ) -> Result<Vec<(String, LanguageEntry)>>

The entries whose key completes the last syllable of prefix: the key starts with prefix and has no syllable boundary after it, so nei h finds nei hou but not nei hou aa. Each comes with its key, heaviest first and by text within a weight, at most limit.

pub fn lookup_completions_into( &self, prefix: &str, limit: usize, result: &mut Vec<(String, LanguageEntry)>, ) -> Result<()>

将补全查询结果写入已有缓冲，保留键和值字符串的容量。

pub fn texts_with_key_prefix(&self, prefix: &str) -> Result<Vec<String>>

键以 prefix 开头的全部词条的文字，不分先后、可能重复。九宫格的笔画筛选用它取「笔顺以这几笔开头的字」：键按前缀落在一段连续区间里，只扫这一段。

pub fn lookup_pattern( &self, pattern: &str, wildcard: char, completions: bool, limit: usize, ) -> Result<Vec<(String, LanguageEntry)>>

匹配 pattern 的词条，wildcard 匹配任意非空格字符，其他字符按字面匹配。补全只匹配键前缀且余下部分不能有音节边界；精确匹配整个键。按权重降序、文字升序返回至多 limit 条。首个通配符前的字面前缀限制扫描范围，只有开头通配符需要整表过滤。

pub fn lookup_pattern_into( &self, pattern: &str, wildcard: char, completions: bool, limit: usize, result: &mut Vec<(String, LanguageEntry)>, ) -> Result<()>

将通配查询写入已有缓冲，复用键与文字的字符串容量；空模式清空结果。

pub fn lookup_readings( &self, positions: &[&[String]], limit: usize, ) -> Result<Vec<(String, LanguageEntry)>>

键按位置逐段取自 positions[i]（以单个空格连接）的词条，各带自己的键；按权重从重到轻，再按文字、键排序，至多 limit 条。每个位置都只有一个读音时就是 lookup 对连接后的键查询，结果与它逐条相同。
