Enum LexicalRole 

#[non_exhaustive]
pub enum LexicalRole {
    Read,
    Write,
}

Role of a lexical binding fact (read or write).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Read

Read access to a lexical variable.

Write

Write access (declaration or assignment) to a lexical variable.
