pub struct Component<'a> { /* private fields */ }

Represents a component in a composition graph.

Implementations

impl<'a> Component<'a>

pub fn from_file(name: impl Into<String>, path: impl AsRef<Path>) -> Result<Self>

Constructs a new component from reading the given file.

pub fn from_bytes(
    name: impl Into<String>,
    bytes: impl Into<Cow<'a, [u8]>>
) -> Result<Self>

Constructs a new component from the given bytes.

pub fn name(&self) -> &str

Gets the name of the component.

Names must be unique within a composition graph.

pub fn path(&self) -> Option<&Path>

Gets the path of the component.

Returns None if the component was not loaded from a file.

pub fn bytes(&self) -> &[u8]

Gets the bytes of the component.

pub fn types(&self) -> TypesRef<'_>

Gets the type information of the component.

pub fn export(
    &self,
    index: impl Into<ExportIndex>
) -> Option<(&str, &str, ComponentExternalKind, u32)>

Gets an export from the component for the given export index.

pub fn export_by_name(
    &self,
    name: &str
) -> Option<(ExportIndex, &str, ComponentExternalKind, u32)>

Gets an export from the component for the given export name.

pub fn exports(
    &self
) -> impl ExactSizeIterator<Item = (ExportIndex, &str, &str, ComponentExternalKind, u32)>

Gets an iterator over the component’s exports.

pub fn import(
    &self,
    index: impl Into<ImportIndex>
) -> Option<(&str, &str, ComponentTypeRef)>

Gets an import from the component for the given import index.

pub fn import_by_name(
    &self,
    name: &str
) -> Option<(ImportIndex, &str, ComponentTypeRef)>

Gets an import from the component for the given import name.

pub fn imports(
    &self
) -> impl ExactSizeIterator<Item = (ImportIndex, &str, &str, ComponentTypeRef)>

Gets an iterator over the component’s imports.
