Enum OpenedFrame 

#[non_exhaustive]
pub enum OpenedFrame {
    Item(Bytes),
    Checkpoint,
    End,
    Failed(RpcErrorBody),
}
Expand description

What the opener made of one framed cbor-seq item.

#[non_exhaustive] because P1 (cratestack#1008) owns this shape.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Item(Bytes)

A data item for codec.decode. In chain mode it is not yet authenticated. It becomes authenticated only when a later Checkpoint or End verifies. The consumer’s mode decides what to do until then (§6): Verified buffers the item, Optimistic releases it and rolls back on a failed checkpoint.

§

Checkpoint

A checkpoint verified. Every item since the previous one is authenticated.

§

End

The terminal checkpoint verified with end: true.

§

Failed(RpcErrorBody)

The terminal checkpoint verified and carries the producer’s error.

fn fg(&self, value: Color) -> Painted<&T>

Set foreground color to white using fg():

use yansi::{Paint, Color};

painted.fg(Color::White);

Set foreground color to white using white().

use yansi::Paint;
