Trait OmmersProvider

pub trait OmmersProvider:
    HeaderProvider
    + Send
    + Sync {
    // Required method
    fn ommers(
        &self,
        id: HashOrNumber,
    ) -> Result<Option<Vec<Self::Header>>, ProviderError>;
}

Available on crate feature provider only.

Client trait for fetching ommers.

Required Methods

fn ommers( &self, id: HashOrNumber, ) -> Result<Option<Vec<Self::Header>>, ProviderError>

Returns the ommers/uncle headers of the given block from the database.

Returns None if block is not found.

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.
