Struct CacheData

#[repr(C)]
pub struct CacheData {
    pub magic: c_uint,
    pub version: c_int,
    pub size: isize,
    pub dir: Offset<u8>,
    pub dirs: Offset<Offset<u8>>,
    pub dirs_count: c_int,

}

The fontconfig cache header, in the raw serialized format.

Fields

magic: c_uint

The magic 4 bytes marking the data as a fontconfig cache.

version: c_int

The cache format version. We support versions 7 and 8.

size: isize

The size of the cache.

dir: Offset<u8>

This cache caches the data of all fonts in some directory. Here is (an offset to) the name of that directory.

dirs: Offset<Offset<u8>>

Here is an offset to an array of offsets to the names of subdirectories.

dirs_count: c_int

How many subdirectories are there?

set: Offset<FontSetData>

An offset to the set of fonts in this cache.

checksum: c_int

A “checksum” of this cache (but really just a timestamp).

checksum_nano: c_int

Another “checksum” of this cache (but really just a more precise timestamp).
