Enum ComponentItemSpec 

pub enum ComponentItemSpec {
    ComponentFunc {
        params: Vec<(String, String)>,
        results: Vec<String>,
    },
    CoreFunc(String),
    Module(String),
    Component {
        imports: HashMap<String, ComponentItemSpec>,
        exports: HashMap<String, ComponentItemSpec>,
    },
    ComponentInstance {
        exports: HashMap<String, ComponentItemSpec>,
    },
    Type(String),
    Resource(String),
    Unknown {
        debug: Option<String>,
    },
}

A serializable and inspectable representation of a WebAssembly Component Model item.

This enum captures the structure of component imports and exports in a way that can be serialized to TOML/JSON, displayed in CLI output, or used for interface validation. It abstracts over low-level wasmtime::component::types::ComponentItem to provide a stable, human-readable format.

Note: This representation is intentionally lossy for MVP. Full WIT type fidelity will be added in later versions using wit-parser.

Variants

ComponentFunc

A WebAssembly component function with named parameters and result types.

Fields

params: Vec<(String, String)>

List of (parameter_name, type_name) pairs.

results: Vec<String>

List of result type names (empty for void functions).

CoreFunc(String)

A core WebAssembly function (not part of the Component Model).

Should generally not appear in valid components, but included for completeness.

Module(String)

A core WebAssembly module embedded within a component.

Represented as a placeholder string in MVP.

Component

A nested WebAssembly component.

Contains its own imports and exports, forming a hierarchical structure.

Fields

imports: HashMap<String, ComponentItemSpec>

Imports declared by the nested component.

exports: HashMap<String, ComponentItemSpec>

Exports provided by the nested component.

ComponentInstance

An instantiated component (e.g., a resolved instance like wasi:cli/stdio).

Only contains exports, as instances are the result of linking.

Fields

exports: HashMap<String, ComponentItemSpec>

The exported items of this instance.

Type(String)

A user-defined type (record, variant, enum, flags, etc.).

Represented as a placeholder string in MVP.

Resource(String)

A resource handle (e.g., file descriptor, socket).

Represented as a placeholder string in MVP.

Unknown

A fallback for unrecognized or unrepresentable component items.

Used to prevent parsing failures when encountering new or malformed items.

Fields

debug: Option<String>

Optional debug information about the unrecognized item.

Trait Implementations

impl Clone for ComponentItemSpec

fn clone(&self) -> ComponentItemSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentItemSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ComponentItemSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ComponentItemSpec

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

Formats the value using the given formatter.

impl FromName for ComponentItemSpec

FromName impl for ComponentItemSpec to enable NamedMap dual-format input.

fn from_name(_name: &str) -> Self

Construct a value from its name.

impl PartialEq for ComponentItemSpec

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

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 ComponentItemSpec

impl StructuralPartialEq for ComponentItemSpec
