[−][src]Struct gluon_vm::macros::MacroEnv
Type containing macros bound to symbols which can be applied on an AST expression to transform it.
Methods
impl MacroEnv[src]
pub fn new() -> MacroEnv[src]
Creates a new MacroEnv
pub fn insert<M>(&self, name: String, mac: M) where
M: Macro + 'static, [src]
M: Macro + 'static,
Inserts a Macro which acts on any occurance of symbol when applied to an expression.
pub fn get(&self, name: &str) -> Option<Arc<dyn Macro>>[src]
Retrieves the macro bound to symbol
pub fn run(
&self,
vm: &Thread,
symbols: &mut Symbols,
expr: &mut SpannedExpr<Symbol>
) -> Result<(), Errors>[src]
&self,
vm: &Thread,
symbols: &mut Symbols,
expr: &mut SpannedExpr<Symbol>
) -> Result<(), Errors>
Runs the macros in this MacroEnv on expr using env as the context of the expansion
