[−][src]Struct poi::Context
Stores variables bound by context.
Fields
vars: Vec<(Arc<String>, Expr)>
Contains the variables in the context.
Implementations
impl Context
[src]
pub fn bind(&mut self, name: &Expr, value: &Expr) -> bool
[src]
Binds patterns of a name
expression to a value
expression.
pub fn substitute(&self, x: &Expr) -> Result<Expr, Error>
[src]
Substitute free occurences of variables in context.
This is used on the right side in a reduction rule.
