Options the memory map is created with

Variants

MapReadable

The memory should be readable

MapWritable

The memory should be writable

MapExecutable

The memory should be executable

MapAddr(*const u8)

Create a map for a specific address range. Corresponds to MAP_FIXED on POSIX.

MapFd(c_int)

Create a memory mapping for a file with a given fd.

MapOffset(usize)

When using MapFd, the start of the map is usize bytes from the start of the file.

MapNonStandardFlags(i32)

On POSIX, this can be used to specify the default flags passed to mmap. By default it uses MAP_PRIVATE and, if not using MapFd, MAP_ANON. This will override both of those. This is platform-specific (the exact values used) and ignored on Windows.
