Helper for looking up and dealing with options.

Required Associated Types

type Item: OptionEntry

Required Methods

fn items(&self) -> &Vec<Loc<Self::Item>>

Provided Methods

fn lookup(&self, name: &str) -> Vec<Loc<&Self::Item>>

fn find_all_strings( &self, diag: &mut Diagnostics, name: &str, ) -> Result<Vec<Loc<String>>, ()>

Find all strings matching the given name.

This enforces that all found values are strings, otherwise the lookup will cause an error.

fn find_all_u32( &self, diag: &mut Diagnostics, name: &str, ) -> Result<Vec<Loc<RpNumber>>, ()>

fn find_all_identifiers( &self, diag: &mut Diagnostics, name: &str, ) -> Result<Vec<Loc<String>>, ()>

Find all identifiers matching the given name.

This enforces that all found values are identifiers, otherwise the lookup will cause an error.

fn find_one_identifier( &self, diag: &mut Diagnostics, name: &str, ) -> Result<Option<Loc<String>>, ()>

Optionally find exactly one identifier matching the given name.

This enforces that all found values are identifiers, otherwise the lookup will cause an error.

fn find_one_string( &self, diag: &mut Diagnostics, name: &str, ) -> Result<Option<Loc<String>>, ()>

fn find_one_u32( &self, diag: &mut Diagnostics, name: &str, ) -> Result<Option<Loc<RpNumber>>, ()>
