Struct Arena 

pub struct Arena {
    pub name: String,
    pub types: Vec<TypeDef>,
    pub functions: Vec<Function>,
    pub children: Vec<Arena>,
}

An arena containing type definitions, functions, and child arenas.

Arenas replace the Package/Interface split with a unified scoping structure. They can be nested to represent hierarchical namespaces.

Fields

name: String

Name of this arena (e.g., “math”, “wasi:cli/stdout”)

types: Vec<TypeDef>

Type definitions in this arena

functions: Vec<Function>

Functions in this arena

children: Vec<Arena>

Child arenas (for hierarchical namespaces)

Implementations

impl Arena

pub fn new(name: impl Into<String>) -> Self

Create a new empty arena with the given name.

pub fn add_type(&mut self, typedef: TypeDef)

Add a type definition to this arena.

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

Add a function to this arena.

pub fn add_child(&mut self, child: Arena)

Add a child arena.

pub fn find_type(&self, name: &str) -> Option<&TypeDef>

Find a type definition by name in this arena.

pub fn find_function(&self, name: &str) -> Option<&Function>

Find a function by name in this arena.

pub fn imports(&self) -> Vec<Function>

Get all imported functions from this package arena.

Returns functions from the “imports” child arena, flattened across interfaces. Each function includes its interface name in the interface field.

pub fn exports(&self) -> Vec<Function>

Get all exported functions from this package arena.

Returns functions from the “exports” child arena, flattened across interfaces. Each function includes its interface name in the interface field.

pub fn imported_function_names(&self, interface_name: &str) -> Vec<String>

Get imported function names for a specific interface.

Useful for subset hash verification - given an interface name, returns the names of functions the actor imports from it.

pub fn exported_function_names(&self, interface_name: &str) -> Vec<String>

Get exported function names for a specific interface.

Trait Implementations

impl Clone for Arena

fn clone(&self) -> Arena

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Arena

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Arena

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Arena

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Arena

fn eq(&self, other: &Arena) -> 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 Arena

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Arena
