Variants

Branch(Box<DecodeNode<L>>, Box<DecodeNode<L>>)

Branch left on 0, right on 1.

StringTerminator

Terminate decoding.

MysteryChar(u8)

Emit a character whose encoding is unspecified and determined by the IO system (but probably Latin-1).

MysteryString(MysteryString)

Emit a string whose encoding is unspecified and determined by the IO system (but probably Latin-1).

UnicodeChar(char)

Emit a Unicode character.

Utf32String(Utf32String)

Emit a Unicode string.

IndirectRef(LabelRef<L>)

Emit the string or call the function found by dereferencing the given address.

DoubleIndirectRef(LabelRef<L>)

Emit the string or call the function found by doubly dereferencing the given address.

IndirectRefWithArgs(LabelRef<L>, Vec<DecodeArg<L>>)

Call the function found by derefencing the given address, passing it the given arguments.

DoubleIndirectRefWithArgs(LabelRef<L>, Vec<DecodeArg<L>>)

Call the function found by doubly derefencing the given address, passing it the given arguments.
