Member Data Documentation

struct_size

uint32_t vgl_disk_cache_create_info::struct_size

reserved

uint32_t vgl_disk_cache_create_info::reserved

directory

const char* vgl_disk_cache_create_info::directory

The directory, UTF-8; created if missing. Required.

source

const vgl_io_interface* vgl_disk_cache_create_info::source

The interface whose reads are cached. Required. The table is copied; the object behind its user_data must stay valid until the cache is destroyed and its reads have completed. With a pool, the cache may call its read from the pool's threads (when an entry on the disk cannot be read), so it must accept reads from any thread.

budget

uint64_t vgl_disk_cache_create_info::budget

Bytes the entries may take on disk. 0 selects 1 GiB.

pool

vgl_thread_pool* vgl_disk_cache_create_info::pool

Optional. Reads and writes the disk on the pool's threads. Null does it in vgl_io_interface.read and on the thread that completes the source's reads.

allocator

const vgl_allocator_interface* vgl_disk_cache_create_info::allocator

Optional. Allocator for the cache and its reads; must be thread-safe.
