pub struct ZeroCopyTcpDecoder { /* private fields */ }Expand description
Zero-copy streaming decoder that reuses buffers
This decoder maintains an internal buffer and only allocates when necessary. Messages are returned as Arc-counted Bytes slices, making cloning extremely cheap.
Implementations§
Source§impl ZeroCopyTcpDecoder
impl ZeroCopyTcpDecoder
Sourcepub fn with_capacity(capacity: usize) -> Self
pub fn with_capacity(capacity: usize) -> Self
Create a new decoder with specific initial capacity
Sourcepub async fn read_message<R: AsyncRead + Unpin>(
&mut self,
reader: &mut R,
) -> Result<TcpRequestMessageZeroCopy>
pub async fn read_message<R: AsyncRead + Unpin>( &mut self, reader: &mut R, ) -> Result<TcpRequestMessageZeroCopy>
Read one complete message with ZERO copies
This method:
- Ensures headers are buffered
- Parses headers in-place (no allocation)
- Ensures entire message is buffered
- Splits off exact message size (zero-copy pointer arithmetic)
- Returns Arc-counted Bytes (cheap to clone)
Sourcepub fn buffer_capacity(&self) -> usize
pub fn buffer_capacity(&self) -> usize
Get the current buffer capacity
Sourcepub fn buffered_len(&self) -> usize
pub fn buffered_len(&self) -> usize
Get the current buffered data size

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

Source§fn bg(&self, value: Color) -> 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.
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);
