Struct TypeIndex 

pub struct TypeIndex { /* private fields */ }

Index over declaration type attributes: sort level and Pi-type arity.

Enables efficient retrieval of all declarations with a given sort level or a given number of explicit arguments.

Implementations

impl TypeIndex

pub fn new() -> Self

Create a new, empty TypeIndex.

pub fn add_by_sort(&mut self, sort_level: u8, id: u32)

Record that declaration id has outermost sort level sort_level.

pub fn add_by_arity(&mut self, arity: u32, id: u32)

Record that declaration id has Pi arity arity.

pub fn lookup_by_sort(&self, sort_level: u8) -> Vec<u32>

Return all declaration ids with outermost sort level sort_level.

pub fn lookup_by_arity(&self, arity: u32) -> Vec<u32>

Return all declaration ids with Pi arity arity.

Trait Implementations

impl Clone for TypeIndex

fn clone(&self) -> TypeIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TypeIndex

fn default() -> Self

Returns the “default value” for a type.
