[−][src]Trait hdk::prelude::AddressableContent

pub trait AddressableContent {
    fn content(&self) -> JsonString;
    fn try_from_content(content: &JsonString) -> Result<Self, JsonError>;

    fn address(&self) -> HashString { ... }
}

can be stored as serialized content the content is the address, there is no "location" like a file system or URL @see https://en.wikipedia.org/wiki/Content-addressable_storage

Required methods

`fn content(&self) -> JsonString`

the Content that would be stored in a ContentAddressableStorage the default implementation covers anything that implements From for JsonString

`fn try_from_content(content: &JsonString) -> Result<Self, JsonError>`

restore/deserialize the original struct/type from serialized Content the default implementation covers anything that implements From for Foo

Provided methods

`fn address(&self) -> HashString`

the Address the Content would be available at once stored in a ContentAddressableStorage default implementation is provided as hashing Content with sha256 the default implementation should cover most use-cases it is critical that there are no hash collisions across all stored AddressableContent it is recommended to implement an "address space" prefix for address algorithms that don't offer strong cryptographic guarantees like sha et. al.
