Struct Settings 

pub struct Settings { /* private fields */ }

A free-standing cpdb settings collection.

Settings are key/value pairs that can be serialised, persisted, and later applied. For per-printer settings see [crate::Printer].

Implementations

impl Settings

pub fn new() -> Result<Self>

Creates a new empty settings collection.

pub fn try_clone(&self) -> Result<Self>

Returns an independent deep copy.

pub fn add_setting(&mut self, key: &str, value: &str) -> Result<()>

Inserts or overwrites a setting.

pub fn clear_setting(&mut self, key: &str) -> Result<bool>

Removes a setting.

Returns Ok(true) when the key existed before this call.

pub fn save_to_disk(&self) -> Result<()>

Persists this settings collection to the cpdb-managed config dir.

The path is chosen by cpdb-libs (see cpdbGetUserConfDir) — callers cannot override it.

pub fn read_from_disk() -> Result<Self>

Loads settings previously written via Settings::save_to_disk.

Trait Implementations

impl Drop for Settings

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
