Enum Command 

#[repr(u8)]
pub enum Command {
    Backspace = 0,
    CommitCandidate = 1,
    CommitRaw = 2,
    Cancel = 3,
    MoveLeft = 4,
    MoveRight = 5,
    MoveHome = 6,
    MoveEnd = 7,
    DeleteForward = 8,
    CycleKanaVariant = 9,
    CommitReading = 10,
    ConvertHanja = 11,

}

Engine-level composition commands (the C++ metasequoia::Command, plus CommitRawWithoutLearning). The host facade numbers them its own way (host::Command).

Variants

Backspace = 0

CommitCandidate = 1

CommitRaw = 2

Cancel = 3

丢弃组字。越南文和藏文的第一次只把显示切回按键原文，下一次才丢弃。

MoveLeft = 4

MoveRight = 5

MoveHome = 6

MoveEnd = 7

DeleteForward = 8

CycleKanaVariant = 9

Japanese only.

CommitReading = 10

Japanese only: commit the kana reading.

ConvertHanja = 11

Open the active scheme’s candidate list, or close it when it is open: the composing syllable’s Hanja in Korean, the conversion’s alternatives in Zhuyin. Schemes without an openable list leave it unhandled. The name stays for the wire and the goldens.

ConversionLeft = 12

整句改字的光标左移一个字：组字的首选是一个字对一个音节的全拼或双拼整句时，第一次进入改字、光标停在最后一个字前，之后每次左移一个字；进不了改字时与 MoveLeft 相同。

ConversionRight = 13

整句改字的光标右移一个字，最远到句末；不在改字里时与 MoveRight 相同。

CommitRawWithoutLearning = 14

像 CommitRaw 一样原样上屏，但不把上屏的字母学成英文词：专用英文里上屏预编辑原文并结束组字（CommitRaw 会学这个词），其余情况与 CommitRaw 相同，SessionOptions::learn_typed_spellings_on_enter 也不起作用。拼写纠错的「回车上屏原文就关掉这段输入的纠错」照常记下。由 crate::Session::command 处理，组字的各条内部路径收不到它。
