pub struct MakeWriterInterceptor { /* private fields */ }Expand description
A MakeWriter that intercepts logs before writing them and allows both to accumulate them in a list or stream to subscribers.
This interceptor can be cloned cheaply, as it contains an Arc inside, and will point to the same logs.
Implementations§
Source§impl MakeWriterInterceptor
impl MakeWriterInterceptor
Sourcepub fn new(accumulate: usize, stream_buffer: usize) -> Self
pub fn new(accumulate: usize, stream_buffer: usize) -> Self
Builds a new MakeWriterInterceptor that will write to Stdout
Sourcepub fn get_last_events(&self) -> VecDeque<String>
pub fn get_last_events(&self) -> VecDeque<String>
Retrieves the last events accumulated by this interceptor
Sourcepub fn subscribe_to_events(&self) -> Option<BroadcastStream<String>>
pub fn subscribe_to_events(&self) -> Option<BroadcastStream<String>>
Subscribes to events until the returned stream is closed
This method will return None only if the writer has been initialized with stream_buffer = 0

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().

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};

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().

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);
