Struct AirModule 

pub struct AirModule {
    pub id: ModuleId,
    pub name: Option<String>,
    pub functions: Vec<AirFunction>,
    pub globals: Vec<AirGlobal>,
    pub source_files: Vec<SourceFile>,
    pub type_hierarchy: Vec<TypeHierarchyEntry>,
    pub constants: BTreeMap<ValueId, Constant>,
    pub types: BTreeMap<TypeId, AirType>,
    pub target_pointer_width: u32,
    pub function_index: BTreeMap<FunctionId, usize>,
    pub name_index: BTreeMap<String, usize>,
}

An AIR module — the top-level container for a compilation unit.

Fields

id: ModuleId

Unique module identifier.

name: Option<String>

Optional module name.

functions: Vec<AirFunction>

Functions in this module.

globals: Vec<AirGlobal>

Global variables/constants.

source_files: Vec<SourceFile>

Source files referenced by spans.

type_hierarchy: Vec<TypeHierarchyEntry>

Type hierarchy entries for CHA (Class Hierarchy Analysis).

constants: BTreeMap<ValueId, Constant>

Inline constants: maps ValueId to constant value.

When a constant (like i32 0) appears as an instruction operand, the frontend records the mapping here so analyses can look up the constant value by ValueId.

types: BTreeMap<TypeId, AirType>

Type table: maps TypeId to AirType definition.

Frontends intern types here during ingestion. Analyses look up types by TypeId for precision improvements. Deterministic ordering via BTreeMap ensures reproducible JSON output.

target_pointer_width: u32

Target pointer width in bytes (4 for 32-bit, 8 for 64-bit). Used by layout computation. Defaults to 8.

function_index: BTreeMap<FunctionId, usize>

Pre-computed index: FunctionId -> position in functions vec. Skipped during serialization; rebuilt on deserialization.

name_index: BTreeMap<String, usize>

Pre-computed index: function name -> position in functions vec. Skipped during serialization; rebuilt on deserialization.

Implementations

impl AirModule

pub fn new(id: ModuleId) -> Self

Create a new module.

pub fn rebuild_function_index(&mut self)

Rebuild the function_index from the current functions vec.

Call this after bulk-modifying functions directly (e.g., assigning a whole Vec<AirFunction>). Not needed when using add_function.

pub fn add_function(&mut self, func: AirFunction)

Add a function, updating the index.

pub fn function(&self, id: FunctionId) -> Option<&AirFunction>

Find a function by ID using the pre-computed index (O(log n)).

Falls back to linear scan if the index is empty (e.g., when the module was constructed via struct literal without rebuilding).

pub fn function_mut(&mut self, id: FunctionId) -> Option<&mut AirFunction>

Find a function by ID (mutable) using the pre-computed index (O(log n)).

Falls back to linear scan if the index is empty.

pub fn function_by_name(&self, name: &str) -> Option<&AirFunction>

Find a function by name using the pre-computed index (O(log n)).

Falls back to linear scan if the index is empty (e.g., when the module was constructed via struct literal without rebuilding).

pub fn global_by_name(&self, name: &str) -> Option<&AirGlobal>

Find a global by name.

pub fn get_type(&self, id: TypeId) -> Option<&AirType>

Look up a type by TypeId.

pub fn is_pointer_type(&self, id: TypeId) -> bool

Check if a TypeId resolves to a pointer-like type (Pointer or Reference).

pub fn instruction_type(&self, inst: &Instruction) -> Option<&AirType>

Get the type of an instruction’s result, if available.

pub fn pointer_value_count(&self) -> usize

Count all values with pointer type in the module.

Uses the type table to determine pointer types. If no type entry exists for a value, it is conservatively not counted as a pointer.

Trait Implementations

impl Clone for AirModule

fn clone(&self) -> AirModule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AirModule

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AirModule

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AirModule

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AirModule

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
