Crate nylon_ring 

ABI-facing types and plugin-definition helpers for Nylon Ring.

Borrowed views such as NrStr and NrBytes do not carry Rust lifetimes across the ABI boundary. Their accessors are therefore unsafe: callers must guarantee that the referenced memory remains valid while the returned borrow is used.

Structs

NrAny

A type-erased value that can hold any data type. This struct is #[repr(C)] and ABI-stable.

NrBufferLease

A host-owned output buffer leased to the plugin.

NrBytes

A byte slice with a pointer and length. This struct is #[repr(C)] and ABI-stable.

NrHostExt

Host extension table for state management. This is an optional extension that does not modify the core ABI.

NrHostVTable

Host callback table.

NrIndexSlot

Index slot for hash table lookup. This struct is #[repr(C)] and ABI-stable.

NrKV

A key-value pair of strings.

NrKVAny

A key-value pair with any type as value. This struct is #[repr(C)] and ABI-stable.

NrMap

A map/dictionary type implemented as a vector of key-value pairs with hash index. This struct is #[repr(C)] and ABI-stable.

NrOwnedBytes

A callee-owned byte buffer handed across the ABI without a copy.

NrPluginInfo

Metadata exported by the plugin through nylon_ring_get_plugin.

NrPluginVTable

Plugin function table.

NrStatus

Status code passed across the Nylon Ring ABI.

NrStr

A UTF-8 string slice with a pointer and length. This struct is #[repr(C)] and ABI-stable.

NrTuple

A tuple of two elements. This struct is #[repr(C)] and ABI-stable.

NrVec

A vector with a pointer, length, and capacity. This struct is #[repr(C)] and ABI-stable.

Enums

NrViewError

Error returned when an ABI string or byte view is malformed.

Constants

ABI_VERSION

The single ABI version implemented by this crate, negotiated through the nylon_ring_get_plugin export. See docs/ABI_EVOLUTION.md.

NR_ENTRY_UNKNOWN

Returned by resolve_entry for a name the plugin does not export.
