pub struct NetworkUdpSocket { /* private fields */ }Expand description
A UDP socket that relays datagrams through the network provider.
Under the hood, the Rust side talks to a local relay socket. Each outbound
datagram is prefixed with a 6-byte address header ([4-byte IPv4][2-byte port BE])
so the relay (Go sidecar) knows where to forward the packet on the tsnet
network. Inbound datagrams arrive with the same header prepended by the relay.
This struct hides the framing — callers use send_to / recv_from with
normal SocketAddr values.
Implementations§
Source§impl NetworkUdpSocket
impl NetworkUdpSocket
Sourcepub async fn send_to(
&self,
data: &[u8],
addr: SocketAddr,
) -> Result<usize, NetworkError>
pub async fn send_to( &self, data: &[u8], addr: SocketAddr, ) -> Result<usize, NetworkError>
Send a datagram to the specified address via the relay.
The relay will forward the datagram to the target on the tsnet network.
Sourcepub async fn recv_from(
&self,
buf: &mut [u8],
) -> Result<(usize, SocketAddr), NetworkError>
pub async fn recv_from( &self, buf: &mut [u8], ) -> Result<(usize, SocketAddr), NetworkError>
Receive a datagram from the relay, returning the payload and sender address.
The relay prepends a 6-byte address header to each inbound datagram.
Sourcepub fn local_addr(&self) -> Result<SocketAddr, NetworkError>
pub fn local_addr(&self) -> Result<SocketAddr, NetworkError>
Return the local address of the underlying relay socket.
Sourcepub fn tsnet_port(&self) -> u16
pub fn tsnet_port(&self) -> u16
Return the tsnet-bound port (the logical port on the Tailscale network).

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().

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>

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.

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);
