Struct move_model::exp_rewriter::ExpRewriter

pub struct ExpRewriter<'env, 'rewriter> { /* private fields */ }

Rewriter for expressions, allowing to substitute locals by expressions as well as instantiate types.

Implementations

impl<'env, 'rewriter> ExpRewriter<'env, 'rewriter>

pub fn new<F>(env: &'env GlobalEnv, replacer: &'rewriter mut F) -> Self where
    F: FnMut(NodeId, RewriteTarget) -> Option<Exp>, 

Creates a new rewriter with the given replacer map.

pub fn set_type_args(self, type_args: &'rewriter [Type]) -> Self

Adds a type argument list to this rewriter. Generic type parameters are replaced by the given types.
