Struct NetBlobAdapterVtable 

#[repr(C)]
pub struct NetBlobAdapterVtable {
    pub store: NetBlobAdapterStoreFn,
    pub fetch: NetBlobAdapterFetchFn,
    pub fetch_range: NetBlobAdapterFetchRangeFn,
    pub exists: NetBlobAdapterExistsFn,
    pub free_buffer: NetBlobAdapterFreeFn,
}

Function-pointer-table the C-side caller passes to net_blob_register_callback_adapter. The struct is #[repr(C)] for cross-ABI stability.

Fields

store: NetBlobAdapterStoreFn

store(ctx, uri, hash, size, data, data_len) -> c_int

fetch: NetBlobAdapterFetchFn

fetch(ctx, uri, hash, size, &out_data, &out_len) -> c_int

fetch_range: NetBlobAdapterFetchRangeFn

fetch_range(ctx, uri, hash, size, start, end, &out_data, &out_len)

exists: NetBlobAdapterExistsFn

exists(ctx, uri, hash, size, &out_exists) -> c_int

free_buffer: NetBlobAdapterFreeFn

free_buffer(ctx, data, len) — substrate calls this after consuming a buffer the caller returned via fetch / fetch_range.
