pub struct IoStream { /* private fields */ }Expand description
A bidirectional, raw stream to the client.
An instance of IoStream is passed to an IoHandler in response to a
successful upgrade request initiated by responders via
Response::add_upgrade() or the equivalent builder method
Builder::upgrade(). For details on upgrade connections, see
Response#upgrading.
An IoStream is guaranteed to be AsyncRead, AsyncWrite, and
Unpin. Bytes written to the stream are sent directly to the client. Bytes
read from the stream are those sent directly by the client. See
IoHandler for one example of how values of this type are used.

builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.

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

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 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);
