Struct two_face::theme::LazyThemeSet

pub struct LazyThemeSet { /* private fields */ }

A ThemeSet that lazily deserializes/decompresses a single theme at a time

This pattern is already actually used by syntect::parsing::SyntaxSet which deserializes/decompresses syntaxes on demand. Doing this has the benefit of lowering load times when you’re only using a few themes at the expense of slightly larger embedded size due to worse compression

Example

For convenience you can easily convert between a LazyThemeSet and a ThemeSet

use two_face::theme::{extra, LazyThemeSet};

let theme_set: LazyThemeSet = LazyThemeSet::from(extra());
let syntect_theme_set = syntect::highlighting::ThemeSet::from(&theme_set);

Implementations

impl LazyThemeSet

pub fn get(&self, name: &str) -> Option<&Theme>

Access a single theme from the set

Calling this multiple times for the same theme will only deserialize and decompress the theme once

Example

use two_face::theme::{extra, LazyThemeSet};

let theme_set = LazyThemeSet::from(extra());
// Loads the theme
let nord1 = theme_set.get("Nord").unwrap();
// Reuses the same loaded theme
let nord2 = theme_set.get("Nord").unwrap();

pub fn theme_names(&self) -> impl Iterator<Item = &str>

Iterate over all the theme names included in the set

Example

use two_face::theme::{extra, LazyThemeSet};

let theme_set = LazyThemeSet::from(extra());
// Nord should be included
assert!(theme_set.theme_names().find(|&name| name == "Nord").is_some());
