Implementations§
Source§impl<A> FramedConn<A>
impl<A> FramedConn<A>
Sourcepub fn new(inner: Conn<A>) -> FramedConn<A>
pub fn new(inner: Conn<A>) -> FramedConn<A>
Constructs a new framed connection.
The underlying connection, inner
, is expected to be something like a
TCP stream. Anything that implements AsyncRead
and AsyncWrite
will do.
Sourcepub async fn recv(&mut self) -> Result<Option<FrontendMessage>, Error>
pub async fn recv(&mut self) -> Result<Option<FrontendMessage>, Error>
Reads and decodes one frontend message from the client.
Blocks until the client sends a complete message. If the client
terminates the stream, returns None
. Returns an error if the client
sends a malformed message or if the connection underlying is broken.
§Cancel safety
This method is cancel safe. The returned future only holds onto a reference to thea underlying stream, so dropping it will never lose a value.
https://docs.rs/tokio-stream/latest/tokio_stream/trait.StreamExt.html#cancel-safety-1
Sourcepub async fn send<M>(&mut self, message: M) -> Result<(), Error>where
M: Into<BackendMessage>,
pub async fn send<M>(&mut self, message: M) -> Result<(), Error>where
M: Into<BackendMessage>,
Encodes and sends one backend message to the client.
Note that the connection is not flushed after calling this method. You
must call FramedConn::flush
explicitly. Returns an error if the
underlying connection is broken.
Please use StateMachine::send
instead if calling from StateMachine
,
as it applies session-based filters before calling this method.

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()
.
use yansi::Paint;
painted.white();

.
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()

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();

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;

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.
fn clear(&self) -> Painted<&T>
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);
