Enum ctru::os::MemRegion

#[non_exhaustive]
#[repr(u8)]
pub enum MemRegion {
    All = 0,
    Application = 1,
    System = 2,
    Base = 3,
}

A region of memory. Most applications will only use Application memory, but the other types can be used to query memory usage information. See https://www.3dbrew.org/wiki/Memory_layout#FCRAM_memory-regions_layout for more details on the different types of memory.

Example

let all_memory = ctru::os::MemRegion::All;

assert!(all_memory.size() > 0);
assert!(all_memory.used() > 0);
assert!(all_memory.free() > 0);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

All = 0

All memory regions.

Application = 1

APPLICATION memory.

System = 2

SYSTEM memory.

Base = 3

BASE memory.
