Struct LazyBlock 

pub struct LazyBlock<Header, Extrinsic> {
    pub header: Header,
    pub extrinsics: Vec<OpaqueExtrinsic>,
    /* private fields */
}

Abstraction over a substrate block that allows us to lazily decode its extrinsics.

Fields

header: Header

extrinsics: Vec<OpaqueExtrinsic>

The accompanying extrinsics.

Implementations

impl<Header, Extrinsic: Into<OpaqueExtrinsic>> LazyBlock<Header, Extrinsic>

pub fn new(header: Header, extrinsics: Vec<Extrinsic>) -> Self
