Options the memory map is created with

Variants

MapReadable

[−] Expand description

The memory should be readable

MapWritable

[−] Expand description

The memory should be writable

MapExecutable

[−] Expand description

The memory should be executable

MapAddr(*const u8)

[−] Expand description

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

MapFd(c_int)

[−] Expand description

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

MapOffset(usize)

[−] Expand description

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

MapNonStandardFlags(c_int)

[−] Expand description

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.
