Struct PartialBindings 

#[non_exhaustive]
pub struct PartialBindings<'a> {
    pub symbols: BTreeMap<SymbolStackVariable, PartialSymbolStack<'a>>,
}

The symbol stack each variable of unified partial stacks stands for.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

symbols: BTreeMap<SymbolStackVariable, PartialSymbolStack<'a>>

The symbol stack each variable stands for.

Implementations

impl<'a> PartialBindings<'a>

pub fn new() -> Self

No variable bound.

pub fn unify( &mut self, lhs: &PartialSymbolStack<'a>, rhs: &PartialSymbolStack<'a>, ) -> Result<PartialSymbolStack<'a>, UnifyError>

The symbol stack both lhs and rhs match, binding their variables.

Errors

Returns UnifyError when they have no stack in common, leaving the bindings unchanged.

Trait Implementations
