ErasedFilterConfigData

Struct ErasedFilterConfigData 

Source
pub struct ErasedFilterConfigData {
    pub name: String,
    pub size: usize,
    pub value: Option<NonNull<c_void>>,
    /* private fields */
}
Available on crate feature filter only.
Expand description

型を消去した汎用データ。

§Warning

この型は型が全くついていません。 基本的にはFilterConfigDataを使用してください。

Fields§

§name: String

設定名。

§size: usize

データのサイズ。

§Note

1024バイトを超えることはできません。

§value: Option<NonNull<c_void>>

現在の値を指すポインタ。

Implementations§

Source§

impl ErasedFilterConfigData

Source

pub fn new<T: Copy + Default + 'static>(name: String) -> Self

新しく作成します。 valueNone になります。

§Panics

Tが1024バイトを超える場合、パニックします。

Source

pub fn with_default_value<T: Copy + 'static>( name: String, default_value: T, ) -> Self

デフォルト値を指定して新しく作成します。 valueNone になります。

§Panics

Tが1024バイトを超える場合、パニックします。

Source

pub fn default_value(&self) -> &[u8]

デフォルト値のスライスを取得します。

Source

pub unsafe fn into_typed<T: Copy + 'static>(self) -> FilterConfigData<T>

型付きの汎用データに変換します。

§Safety
  • self を消去する前の型Tと同じ型で呼び出す必要があります。
  • Tのサイズがself.sizeと一致している必要があります。
  • self.valueが指すポインタが有効である必要があります。
  • self.default_valueはTとして有効なデータである必要があります。
