Source§impl Record
impl Record
Sourcepub fn encode<B: BufMut>(&self, buf: &mut B) -> Result<(), RecordsError>
pub fn encode<B: BufMut>(&self, buf: &mut B) -> Result<(), RecordsError>
Encode a single record into buf as a varlong length prefix and fields.
§Errors
Returns the underlying protocol error when input is truncated, contains an invalid length or tag, or cannot be encoded for the selected version.
Sourcepub fn encoded_len(&self) -> usize
pub fn encoded_len(&self) -> usize
Predicted total length of this record on the wire, length-prefix plus body.
§Panics
Panics if a value previously validated by the protocol type no longer satisfies its encoded-length or field-range invariant.
Sourcepub fn body_len(&self) -> usize
pub fn body_len(&self) -> usize
Size of this record’s body in bytes: what Kafka’s DefaultRecord calls
sizeOfBodyInBytes, and what its varlong length prefix declares.
The body is the attributes byte, the two deltas, and the key, the value
and the headers, each behind its own length prefix. A null key, value or
header value counts as the one-byte -1 marker. The length prefix
itself is not counted: Record::encoded_len is the prefix and this.
Sourcepub fn decode<B: Buf>(buf: &mut B) -> Result<Self, RecordsError>
pub fn decode<B: Buf>(buf: &mut B) -> Result<Self, RecordsError>
Decode a single record.
buf must be positioned at the record’s varlong length prefix.
§Errors
Returns the underlying protocol error when input is truncated, contains an invalid length or tag, or cannot be encoded for the selected version.

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().
use yansi::Paint;
painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

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 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>
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);
