Enum FATType 

pub enum FATType {
    FAT12,
    FAT16,
    FAT32,
    ExFAT,
}

An enum representing different variants of the FAT filesystem

The logic is essentially the same in all of them, the only thing that changes is the size in bytes of FAT entries, and thus the maximum volume size

Variants

FAT12

One of the earliest versions, originally used all the way back to 1980. This probably won’t be encountered anywhere outside ancient MS-DOS versions or pretty low-size volumes, like microcontrollers

Max volume size: 8 MB

FAT16

Used in many low-size volumes

Min volume size: 8 MB, Max volume size: 16 GB

FAT32

The most commonly-used variant.

Min volume size: 256 MB, Max volume size: 16 TB

ExFAT

An ex-proprietory filesystem that allows for even larger storage sizes and its use is currently on the rise

Not currently supported

Trait Implementations

impl Clone for FATType

fn clone(&self) -> FATType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FATType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FATType

fn eq(&self, other: &FATType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for FATType
