Enum FileError 

#[non_exhaustive]
pub enum FileError {
    Name(NameProblem),
    Outside,
    IntoItself,
    Taken(String),

    Denied,
    NotReadable,
    Missing,
    NoTrash,
    NoRoom,

Why a file operation was not done.

More reasons may be added as more operations arrive, so match with a _ arm and lean on message for the words.

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.

Name(NameProblem)

The name cannot be used.

Outside

The entry would be reached, or land, outside the root folder.

IntoItself

A folder was to go into itself or into a folder below it.

Taken(String)

The target folder already has an entry of this name.

CrossDevice

Moving would cross to another file system, which a rename cannot do; files are not copied.

Denied

The user may not read or change this.

NotReadable

The user may not see what is in this folder.

Missing

It is not there any more: another program took it away while the rows still showed it.

NoTrash

There is no trash this entry can go to: none on this file system, or none at all.

NoRoom

The disk is full.

Stopped

The person said to stop, and what had been written was taken away again.

System(String)

What the operating system said.
