Struct cyfs_base::TypelessObjectDesc

pub struct TypelessObjectDesc { /* private fields */ }

无类型的Buffer对象，丢失了SubDesc和DescContent部分的类型信息 实际上也是可以做到带组合类型信息，不过Owner x Area x Author x PublicKey 一共有 24 种组合类型 不过，既然丢失了类型信息，只提供组合类型信息也只是完成了类型信息的一半， 可以通过提供build的方式重建具体的带类型信息的NamedObject，通过调用者注入具体的类型信息完成完整的重构

Implementations

impl TypelessObjectDesc

丢失了SubDesc类型信息，用成员方法的方式暴露是否含有这些数据

pub fn owner(&self) -> &Option<ObjectId>

pub fn area(&self) -> &Option<Area>

pub fn author(&self) -> &Option<ObjectId>

pub fn version(&self) -> u8

pub fn format(&self) -> u8

pub fn content(&self) -> &Vec<u8>

pub fn convert_to<DescContentT>(
    self
) -> BuckyResult<NamedObjectDesc<DescContentT>>where
    DescContentT: for<'de> RawDecode<'de> + DescContent + Sync + Send + Clone,

pub fn public_key(&self) -> Option<PublicKeyRef<'_>>

Trait Implementations

impl<'de> RawDecodeWithContext<'de, NamedObjectContext> for TypelessObjectDesc

TypelessObjectDesc 解码

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

) -> BuckyResult<(Self, &'de [u8])>

impl RawEncode for TypelessObjectDesc

TypelessObjectDesc 用于计算ID用的编码

• [1] ctx 部分包含obj_type, obj_flags 信息(前5bits为0，区别于NamedObject里的ctx.obj_flags)
• [2] 其余部分为desc本身的编码
