Required Methods

    &self,
    buf: &'a mut [u8],
    _: &mut Context,
    purpose: &Option<RawEncodePurpose>
) -> BuckyResult<&'a mut [u8]>

Provided Methods

Implementors

impl RawEncodeWithContext<NamedObjectContext> for ObjectSigns

impl RawEncodeWithContext<NamedObjectContext> for TypelessObjectDesc

TypelessObjectDesc 编码

• [1] ctx 部分来自NamedObject里的ctx
• [2] 其余部分为desc本身的编码

impl<'de, B, O> RawEncodeWithContext<NamedObjectBodyContext> for ObjectMutBody<B, O> where
    B: RawEncode + BodyContent,
    O: ObjectType, 

impl<O> RawEncodeWithContext<NamedObjectContext> for NamedObjectBase<O> where
    O: ObjectType,
    O::DescType: RawEncodeWithContext<NamedObjectContext>,
    O::ContentType: RawEncode + BodyContent, 

impl<T> RawEncodeWithContext<NamedObjectContext> for NamedObjectDesc<T> where
    T: DescContent + RawEncode, 

NamedObjectDesc 的 编码

• ctx: NamedObjectContext 从上层 NamedObjectBase 里传入编码的上下文
• 通过 ctx 压缩Option字段的编码
