}Expand description
A peer as seen by application code.
This is a simplified projection of the internal PeerState that hides
session-layer internals. Applications use this to display peer lists and
resolve peer IDs for send() / open_tcp().
RFC 017 introduced device_id and device_name derived from the hello
envelope — these are populated once the WebSocket link comes up. Before
that, they fall back to the legacy Tailscale ID / hostname pair so
application code has something to display even for not-yet-connected
peers.
Fields§
§id: StringLegacy per-peer ID. Kept for back-compat with call sites that
destructure peer.id; new code should prefer device_id
directly. Equal to device_id once the hello has landed; equal to
the Tailscale stable ID beforehand.
name: StringLegacy name (the Layer 3 Tailscale hostname — the slug). New code
should prefer device_name.
device_id: StringStable per-device ULID (RFC 017 §5.4) from the hello envelope. Falls back to the Tailscale stable ID until the hello handshake completes.
device_name: StringHuman-readable device name from the hello envelope (original Unicode form, NOT the slug). Falls back to the hostname until the hello completes.
tailscale_id: StringTailscale stable node ID — escape hatch for diagnostics and the transport routing key.
ip: IpAddrNetwork IP address.
online: boolWhether the peer is online (from Layer 3).
ws_connected: boolWhether there is an active WebSocket connection.
connection_type: StringConnection type description (e.g., "direct" or "relay:ord").
os: Option<String>Operating system, if known. Prefers the hello envelope’s value and falls back to Layer 3.
last_seen: Option<String>Last time the peer was seen online (RFC 3339 string).

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

painted.white();Source§fn bright_black(&self) -> Painted<&T>

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
