Struct ValueRef

pub struct ValueRef<'v> { /* private fields */ }

Reference to a value, or to a sub-value of a value.

Implementations

impl ValueRef<'_>

pub fn is_unit(&self) -> bool

Check if the value is a unit.

pub fn as_left(&self) -> Option<Self>

pub fn as_right(&self) -> Option<Self>

Access the inner value of a right sum value.

pub fn as_product(&self) -> Option<(Self, Self)>

Access the inner values of a product value.

pub fn to_value(&self) -> Value

Convert the reference back to a value.

pub fn to_word(&self) -> Option<Word>
