Struct CardSourceError 

pub struct CardSourceError {
    pub endpoint: String,
    pub reason: String,
}

Why a card could not be read.

One variant on purpose: from the caller’s side every failure means the same thing — the agent did not hand over a card — and the underlying reason is diagnostic text, not something to branch on.

Fields

endpoint: String

The endpoint that was asked.

reason: String

What went wrong, as reported by the transport.
