Struct ctaphid::Options

#[non_exhaustive]
pub struct Options {
    pub nonce: [u8; 8],
    pub timeout: Option<Duration>,
}

Connection options for a CTAPHID device.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

nonce: [u8; 8]

The nonce for the initilization of the communication channel.

Per default, this is generated using rand_core::OsRng.

timeout: Option<Duration>

The timeout for receiving a packet from the device.

Per default, this is set to one second.
