Struct Theme 

pub struct Theme { /* private fields */ }

A theme with common semantic tokens and canonical component presentations.

A theme carries no application-specific slot. Applications extend it by implementing TextThemeRole for their own role type and deriving the style inside TextThemeRole::resolve; see the module documentation for the conventions that follow from that.

Implementations

impl Theme

pub fn from_tokens(tokens: SemanticTokens) -> Self

pub fn new(tokens: SemanticTokens, components: ComponentTheme) -> Self

pub fn tokens(&self) -> &SemanticTokens

pub fn components(&self) -> &ComponentTheme

pub fn list<T>(&self, list: &List<T>) -> View

where T: Display,

Composes a list with this theme’s canonical presentation.

pub fn tree<T>(&self, tree: &Tree<T>) -> View

where T: Display,

Composes a tree with this theme’s canonical presentation.

pub fn table<T>(&self, table: &Table<T>) -> View

where T: TableRow,

Composes a table with this theme’s canonical presentation.

pub fn scrollbar(&self, scrollbar: &Scrollbar) -> View

Composes a scrollbar with this theme’s canonical presentation.

pub fn text_style<R>(&self, role: R) -> TextStyle

where R: TextThemeRole,

Resolves one role against this theme.

The style is returned by value because application roles derive their style rather than reading it from a stored table. Consumers that resolve roles inside a draw loop should resolve once into their own cache and borrow from it; Theme::components also exposes built-in styles as borrows.

pub fn block_style<R>(&self, role: R) -> BlockStyle

where R: BlockThemeRole,

Resolves one geometry-bearing role against this theme.

Trait Implementations

impl Clone for Theme

fn clone(&self) -> Theme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Theme

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

Formats the value using the given formatter.

impl PartialEq for Theme

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