Module token 

Parsed snippet body: the token stream a crate::parse::parse produces and crate::render::render walks.

Tokens map 1:1 to TextMate / LSP snippet syntax constructs plus a tail Literal for plain text runs:

Construct	Token
foo bar	SnippetToken::Literal
$1, $0, $99	SnippetToken::Tabstop
${1:default text}	SnippetToken::Placeholder
${1|opt1,opt2,opt3|}	SnippetToken::Choice
$VAR / ${VAR}	SnippetToken::Variable
${VAR:fallback}	SnippetToken::Variable (with default)
${1/pat/repl/flags} / ${VAR/pat/repl/flags}	SnippetToken::Transform
\$, \\, \}	unescaped → contributes to a SnippetToken::Literal

Structs

ChoiceOption

Choice placeholder option (${1|opt1,opt2,opt3|} -> three options). Stored verbatim; the picker UI renders them as alternatives.

SnippetBody

A parsed snippet body. Just a wrapper over the token vec so the type signature in registry / load / render stays readable.

Enums

SnippetToken

One token from a parsed snippet body.

TransformTarget

What a Transform token applies to.
