Trait Header

pub trait Header: Serialize {
    type Id: BlockId;
    type Date: BlockDate;
    type ChainLength: ChainLength;
    type Version;

    // Required methods
    fn id(&self) -> Self::Id;
    fn parent_id(&self) -> Self::Id;
    fn date(&self) -> Self::Date;
    fn version(&self) -> Self::Version;
    fn chain_length(&self) -> Self::ChainLength;
}

Trait identifying the block header type.

Required Associated Types

type Id: BlockId

The block header id.

type Date: BlockDate

The block date.

type ChainLength: ChainLength

the length of the blockchain (number of blocks)

type Version

the type associated to the version of a block

Required Methods

fn id(&self) -> Self::Id

Retrieves the block’s header id.

fn parent_id(&self) -> Self::Id

get the parent block identifier (the previous block in the blockchain).

fn date(&self) -> Self::Date

Retrieves the block’s date.

fn version(&self) -> Self::Version

access the version of a given block

fn chain_length(&self) -> Self::ChainLength

get the block’s chain length. The number of block created following this thread of blocks on the blockchain (including Self).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
