Enum Kind 

pub enum Kind {
    Style = 0,
    Font = 1,
    Image = 2,
    Script = 3,
}

リソースの種別。値が小さいほど優先。

【2026-08-05】CSS を非同期取得にしたとき、CSS がフォント 8 本・画像と 同じ枠を奪い合って到着が遅すぎ、スタイル付きのレイアウトが 実行時間内に始まらなかった（ログの行番号で確認。 「カスケード開始 ルール数=2403」の後に完了行が出ない）。

CSS はレイアウトに必須なので最優先。 フォントは文字の見た目に直結するので次。 画像は無くても文章が読める。JS は最後。

Variants

Style = 0

スタイルシート。レイアウトに必須。

Font = 1

Web フォント。

Image = 2

画像。

Script = 3

スクリプト。

Implementations

impl Kind

pub fn priority(self) -> u8

Trait Implementations

impl Clone for Kind

fn clone(&self) -> Kind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Kind

impl Debug for Kind

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

Formats the value using the given formatter.

impl Eq for Kind

impl Ord for Kind

fn cmp(&self, other: &Kind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Kind

fn eq(&self, other: &Kind) -> 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 PartialOrd for Kind

fn partial_cmp(&self, other: &Kind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
