Struct RawPluginMetadata 

#[repr(C)]
pub struct RawPluginMetadata {
    pub name_ptr: *const u8,
    pub name_len: usize,
    pub version_ptr: *const u8,
    pub version_len: usize,
    pub description_ptr: *const u8,
    pub description_len: usize,
    pub abi_version: u32,
}

#[repr(C)] metadata struct returned by audio_plugin_metadata.

Each string is a (ptr, len) pair pointing into a byte buffer owned by the plugin for the lifetime of the loaded library ('static from the host’s perspective). The host copies the bytes out into owned Strings immediately (see raw_to_metadata) and never retains the pointers.

Layout

The fields are ordered to match the C declaration plugin authors write:

struct raw_plugin_metadata {
    const uint8_t *name_ptr;        size_t name_len;
    const uint8_t *version_ptr;     size_t version_len;
    const uint8_t *description_ptr; size_t description_len;
    uint32_t abi_version;
};

Fields

name_ptr: *const u8

Pointer to the UTF-8 plugin name bytes.

name_len: usize

Length in bytes of the name_ptr range.

version_ptr: *const u8

Pointer to the UTF-8 version bytes.

version_len: usize

Length in bytes of the version_ptr range.

description_ptr: *const u8

Pointer to the UTF-8 description bytes.

description_len: usize

Length in bytes of the description_ptr range.

abi_version: u32

Encoded ABI version the plugin was built against.
