Struct abi_stable::for_examples::Module_Ref

#[repr(transparent)]
pub struct Module_Ref(pub PrefixRef<Module_Prefix>);

This is the pointer to the prefix of Module.

This is automatically generated documentation,by the StableAbi derive macro.

Creating a compiletime-constant

You can look at the docs in ::abi_stable::docs::prefix_types to see how you can construct and use this and similar types.
More specifically in the “constructing a module” example or the “Constructing a vtable” example

Implementations

impl Module_Ref

pub fn first(&self) -> ROption<usize>

Accessor method for the Module::first field.This is for a field which always exists.

pub fn second(&self) -> RStr<'static>

Accessor method for the Module::second field.This is for a field which always exists.

impl Module_Ref

pub fn _prefix_type_layout(self) -> &'static PTStructLayout

Accessor to get the layout of the type,used for error messages.

pub fn third(&self) -> Option<usize>

Accessor method for the Module::third field.Returns Some(field_value) if the field exists,None if it does not.

Trait Implementations

impl Clone for Module_Ref

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl GetPointerKind for Module_Ref

type PtrTarget = WithMetadata_<Module_Prefix, Module_Prefix>

What this pointer points to.

type Kind = PK_Reference

The kind of the pointer.

const KIND: PointerKind = <Self::Kind as PointerKindVariant>::VALUE

The value-level version of the Kind associated type.

impl GetStaticEquivalent_ for Module_Ref

where Module: PrefixTypeTrait,

type StaticEquivalent = PrefixRef<_static_Module>

The 'static equivalent of Self

impl PrefixRefTrait for Module_Ref

type PrefixFields = Module_Prefix

A struct that contains all the fields of some other struct up to the field annotated with #[sabi(last_prefix_field)] inclusive.

fn from_prefix_ref(this: PrefixRef<Self::PrefixFields>) -> Self

Converts a PrefixRef to Self

fn to_prefix_ref(self) -> PrefixRef<Self::PrefixFields>

Converts Self to a PrefixRef

impl RootModule for Module_Ref

fn root_module_statics() -> &'static RootModuleStatics<Module_Ref>

Gets the statics for Self.

const BASE_NAME: &'static str = "example_root_module"

The name of the dynamic library,which is the same on all platforms. This is generally the name of the implementation crate.

const NAME: &'static str = "example_root_module"

The name of the library used in error messages.

const VERSION_STRINGS: VersionStrings = _

The version number of the library that this is a root module of.

const CONSTANTS: RootModuleConsts = _

All the constants of this trait and supertraits.

const CONSTANTS_NO_ABI_INFO: RootModuleConsts = _

Like Self::CONSTANTS, except without including the type layout constant for the root module.

fn get_module() -> Option<Self>

Gets the root module,returning None if the module is not yet loaded.

fn get_raw_library() -> Option<&'static RawLibrary>

Gets the RawLibrary of the module, returning None if the dynamic library failed to load (it doesn’t exist or layout checking failed).

fn get_library_path(directory: &Path) -> PathBuf

Returns the path the library would be loaded from,given a directory(folder).

fn load_module_with<F, E>(f: F) -> Result<Self, E>

where F: FnOnce() -> Result<Self, E>,

Loads the root module,with a closure which either returns the root module or an error.

fn load_from(where_: LibraryPath<'_>) -> Result<Self, LibraryError>

Loads this module from the path specified by where_, first loading the dynamic library if it wasn’t already loaded.

fn load_from_directory(where_: &Path) -> Result<Self, LibraryError>

Loads this module from the directory specified by where_, first loading the dynamic library if it wasn’t already loaded.

fn load_from_file(path_: &Path) -> Result<Self, LibraryError>

Loads this module from the file at path_, first loading the dynamic library if it wasn’t already loaded.

fn initialization(self) -> Result<Self, LibraryError>

Defines behavior that happens once the module is loaded.

impl StableAbi for Module_Ref

where Module: PrefixTypeTrait,

type IsNonZeroType = True
