Struct ProfileStore 

pub struct ProfileStore { /* private fields */ }

The Storage of the profile in use: each key is read and written as that profile’s (ProfileId::key), and list lists only its keys, without their prefix. What stays with the computer (the list of profiles, whatever the game keeps per computer) goes through computer.

Implementations

impl ProfileStore

pub fn new(computer: Box<dyn Storage>, profile: ProfileId) -> Self

The storage of profile in computer.

pub fn profile(&self) -> ProfileId

The profile whose keys this reads and writes.

pub fn computer(&self) -> &dyn Storage

The computer’s own storage, for what no profile holds.

pub fn computer_mut(&mut self) -> &mut dyn Storage

computer, to write.

pub fn into_computer(self) -> Box<dyn Storage>

The computer’s storage, for the next launch.

Trait Implementations

impl Debug for ProfileStore

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

Formats the value using the given formatter.

impl Default for ProfileStore

An empty MemoryStorage, as the first profile’s.

fn default() -> Self

Returns the “default value” for a type.

impl Storage for ProfileStore

fn read(&self, key: &str) -> Result<Option<String>, StorageError>

The value stored at key, or None if nothing has been written there (or it was deleted).

fn write(&mut self, key: &str, value: &str) -> Result<(), StorageError>

Stores value at key, replacing whatever was there.

fn delete(&mut self, key: &str) -> Result<(), StorageError>

Removes key. Not an error if it didn’t exist.

fn list(&self) -> Result<Vec<String>, StorageError>

Every key currently stored, in no particular order.
