Struct NameFixer 

pub struct NameFixer { /* private fields */ }

Dictionary-based helper that adapts names to guarantee they’re unique.

Implementations

impl NameFixer

pub fn new() -> Self

Creates a new instance of NameFixer pre-filled with reserved words of the Rust language, so that variables don’t have a forbidden name.

See new_empty() for a version that isn’t pre-filled with reserved words.

pub fn new_empty() -> Self

Creates a new instance of NameFixer that is not pre-filled with Rust reserved words. This name fixer can be used when the names will be prefixed or postfixed in a way that guarantees they’re not forbidden.

See new() for the safer version pre-filled with reserved words.

pub fn add(&mut self, name: String)

Adds a name to the internal dictionary without checking whether it already existed or not. Use this method to pre-fill existing names.

pub fn remove(&mut self, name: &str) -> bool

Removes a name from the internal dictionary. Returns true if the name was in the dictionary.

pub fn contains(&self, name: &str) -> bool

Checks if a name is already in the internal dictionary.

pub fn get_unique_name(&mut self, name: String) -> String

Returns name if it’s unique, or adds a suffix number first to make sure it’s unique.

pub fn get_unique_name_num(&mut self, name: String) -> String

Returns name followed by “1” if it’s unique, or adds another incremental suffix number to make sure it’s unique.

pub fn get_unique_name_unum(&mut self, name: String) -> String

Returns name followed by “_1” if it’s unique, or finds another incremental suffix number to make sure it’s unique.

pub fn add_number(s: &mut String, num: usize)

Adds _{num} or {num} to the string depending on its last character, whether it’s respectivelly a digit or not. Used if we want to make sure a digit isn’t added to an identifier ending with a number, which would make it confusing.
