Enum FsReader 

#[non_exhaustive]
pub enum FsReader<R> {
    Ext(Reader<R>),
    Fat(Reader<R>),
    ExFat(Reader<R>),
    Btrfs(Reader<R>),
}

An open filesystem, as whichever family claimed the image.

Present only in a build that compiles in at least one family: with none, there is nothing an image could be opened as, and detect already answers Unrecognized for every source.

Each variant carries that family’s own reader, whole: nothing is hidden behind a common interface, so a caller that has matched its way to one has everything that family offers. What every variant does share is FsTree, so an extraction need not match at all.

The enum is #[non_exhaustive], and a build compiles in the variants of the families it compiles in — so a match carries a wildcard arm, and adding a family is not a breaking change.

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.

Ext(Reader<R>)

An ext2, ext3, or ext4 filesystem.

Fat(Reader<R>)

A FAT12, FAT16, or FAT32 volume.

ExFat(Reader<R>)

An exFAT volume.

Btrfs(Reader<R>)

A btrfs filesystem.
