Trait InherentDigest

pub trait InherentDigest {
    type Value: Send + Sync + 'static;

    // Required methods
    fn from_inherent_data(
        inherent_data: &InherentData,
    ) -> Result<Vec<DigestItem>, Box<dyn Error + Send + Sync>>;
    fn value_from_digest(
        digests: &[DigestItem],
    ) -> Result<Self::Value, Box<dyn Error + Send + Sync>>;
}

Defines parts of inherent data that should be included in header digest

Required Associated Types

type Value: Send + Sync + 'static

Rust type of the inherent digest value

Required Methods

fn from_inherent_data( inherent_data: &InherentData, ) -> Result<Vec<DigestItem>, Box<dyn Error + Send + Sync>>

Construct digest items from block’s inherent data

fn value_from_digest( digests: &[DigestItem], ) -> Result<Self::Value, Box<dyn Error + Send + Sync>>

Retrieve value from digests

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.
