Enum ThemeNameProvider

pub enum ThemeNameProvider {
    KDE,
    GTK,
    User(String),
    Custom(Box<dyn Fn() -> Result<String, Box<dyn StdError + Send + Sync>> + Send + Sync>),
}

Enum that provides a theme name to IconLoader. It can either load the system theme name from the KDE or GTK config files or provide a fixed string or a theme name yielded by a completely customizable function. The last option allows users to load their own config files for example.

Variants

KDE

Use the ‘~/.config/kdeglobals’ file to determine the theme name.

GTK

Use the ‘~/.config/gtk-3.0/settings.ini’ file to determine the theme name.

User(String)

A theme name provided by the user.

Custom(Box<dyn Fn() -> Result<String, Box<dyn StdError + Send + Sync>> + Send + Sync>)

A custom function that returns a theme name or an error.

Implementations

impl ThemeNameProvider

pub fn user(string: impl Into<String>) -> Self

Creates a new ThemeNameProvider that provides the given string as theme name.

pub fn custom<F, S, E>(f: F) -> Self

where F: Fn() -> Result<S, E> + Send + Sync + 'static, S: Into<String>, E: StdError + Send + Sync + 'static,

Creates a new custom ThemeNameProvider from the given function.

Trait Implementations

impl Debug for ThemeNameProvider

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

Formats the value using the given formatter.

impl Default for ThemeNameProvider

fn default() -> Self

Returns the “default value” for a type.

impl From<&str> for ThemeNameProvider

fn from(string: &str) -> Self

Converts to this type from the input type.

impl<F, S, E> From<F> for ThemeNameProvider

where F: Fn() -> Result<S, E> + Send + Sync + 'static, S: Into<String>, E: StdError + Send + Sync + 'static,

fn from(f: F) -> Self

Converts to this type from the input type.

impl From<String> for ThemeNameProvider

fn from(string: String) -> Self

Converts to this type from the input type.

impl PartialEq for ThemeNameProvider

fn eq(&self, other: &Self) -> 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.
