Struct PresenceOptions 

pub struct PresenceOptions {
    pub mode: PresenceMode,
    pub cache_ttl_secs: u64,
    pub reason: String,
}

Options controlling the user-presence prompt for SignerHandle::sign_with_presence.

The mode field determines whether a prompt fires; cache_ttl_secs controls how long a successful authentication suppresses subsequent prompts (macOS only); reason is the human-readable string shown in the biometric dialog.

Fields

mode: PresenceMode

Controls when the biometric/PIN prompt fires.

cache_ttl_secs: u64

How long a successful authentication suppresses subsequent prompts. Effective only on macOS (LAContext TTL); ignored on other platforms. 0 means prompt on every call.

reason: String

Human-readable reason shown in the Touch ID / Windows Hello dialog.

Implementations

impl PresenceOptions

pub fn strict(reason: impl Into<String>) -> Self

Create options that always prompt (no caching). Equivalent to PresenceMode::Strict with cache_ttl_secs = 0.

pub fn cached(reason: impl Into<String>, ttl_secs: u64) -> Self

Create options that cache a successful authentication for ttl_secs seconds before prompting again. Uses PresenceMode::Cached.
