Trait EraBlockReader 

pub trait EraBlockReader<BH, BB, R> {
    // Required method
    fn blocks<M: EraMeta + ?Sized>(
        meta: &M,
        decode_receipts: bool,
    ) -> Result<impl Iterator<Item = Result<(BH, BB, Option<Vec<R>>)>>>;
}

Reads execution (header, body, receipts) tuples out of an ERA file.

receipts is None when decode_receipts is false, or the file has none (.era never does; .ere receipts are optional). decode_receipts = false skips decoding entirely.

Per-format seam of the import pipeline.

Required Methods

fn blocks<M: EraMeta + ?Sized>( meta: &M, decode_receipts: bool, ) -> Result<impl Iterator<Item = Result<(BH, BB, Option<Vec<R>>)>>>

Opens the ERA file at meta and iterates its execution blocks.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
