Trait Lib 

pub trait Lib {
    // Required methods
    fn manifest(&self) -> LibManifest;
    fn load(&self, cx: &mut LoadCx, linker: &mut Linker<'_>) -> Result<()>;

    // Provided method
    fn unload(&self, _cx: &mut Cx, _linker: &mut Linker<'_>) -> Result<()> { ... }
}

The contract every loadable library implements.

A library presents its LibManifest and wires its behavior into the registry through a Linker during load. The kernel defines this contract; libraries provide the behavior.

Required Methods

fn manifest(&self) -> LibManifest

Returns the library’s manifest.

fn load(&self, cx: &mut LoadCx, linker: &mut Linker<'_>) -> Result<()>

Registers the library’s exports against the registry via linker.

Provided Methods

fn unload(&self, _cx: &mut Cx, _linker: &mut Linker<'_>) -> Result<()>

Tears down external resources that cannot be represented in the registry’s recorded load delta.

Normal export removal is driven by Registry::unload, which retracts the committed registry records for a loaded LibId. Libraries should only override this hook when they acquire external resources outside the registry receipt; the default means there is no custom external teardown.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
