Struct PrinterConfig 

pub struct PrinterConfig {
    pub last_printer_id: Option<String>,
    pub last_backend: Option<String>,
    pub global_settings: HashMap<String, String>,
    pub printer_settings: HashMap<String, HashMap<String, String>>,
}

Available on crate feature zbus-backend only.

Saved user preferences for the print dialog.

Keeps track of the last selected printer, global default settings, and per-printer customized settings (e.g. paper size, quality options).

Fields

last_printer_id: Option<String>

Last-used printer identifier

last_backend: Option<String>

Last-used backend name

global_settings: HashMap<String, String>

Global settings that apply to all printers unless overridden (e.g. "copies" => "1")

printer_settings: HashMap<String, HashMap<String, String>>

Per-printer settings keyed by "printer_id@backend"

Implementations

impl PrinterConfig

pub fn new() -> Self

Creates a new empty PrinterConfig.

pub fn has_printer(&self) -> bool

Returns true if this config has a saved printer.

pub fn set_last_printer(&mut self, printer_id: &str, backend: &str)

Sets the last-used printer and backend.

pub fn get_global_setting(&self, key: &str) -> Option<&str>

Gets a global setting.

pub fn set_global_setting(&mut self, key: String, value: String)

Sets a global setting.

pub fn get_settings_for( &self, printer_id: &str, backend: &str, ) -> HashMap<String, String>

Gets the merged settings for a specific printer.

This combines the global_settings with the printer-specific settings, where printer-specific values override global values.

pub fn set_settings_for( &mut self, printer_id: &str, backend: &str, settings: HashMap<String, String>, )

Updates or replaces the settings for a specific printer.

pub fn set_setting_for( &mut self, printer_id: &str, backend: &str, key: String, value: String, )

Sets or updates a single setting for a specific printer.

pub fn get_setting_for( &self, printer_id: &str, backend: &str, key: &str, ) -> Option<&str>

Gets a specific setting for a printer (printer-specific or global fallback).

pub fn remove_settings_for(&mut self, printer_id: &str, backend: &str)

Removes all printer-specific settings stored for a printer.

Trait Implementations

impl Clone for PrinterConfig

fn clone(&self) -> PrinterConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrinterConfig

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

Formats the value using the given formatter.

impl Default for PrinterConfig

fn default() -> PrinterConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PrinterConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PrinterConfig

fn eq(&self, other: &PrinterConfig) -> 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 Serialize for PrinterConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
