pub struct ReadDir(/* private fields */);Expand description
Reads the entries in a directory.
This struct is returned from the read_dir function of this module and
will yield instances of DirEntry. Through a DirEntry information
like the entry’s path and possibly other metadata can be learned.
A ReadDir can be turned into a Stream with ReadDirStream.
§Errors
This stream will return an Err if there’s some sort of intermittent
IO error during iteration.
Implementations§
Source§impl ReadDir
impl ReadDir
Sourcepub fn poll_next_entry(
&mut self,
cx: &mut Context<'_>,
) -> Poll<Result<Option<DirEntry>, Error>>
pub fn poll_next_entry( &mut self, cx: &mut Context<'_>, ) -> Poll<Result<Option<DirEntry>, Error>>
Polls for the next directory entry in the stream.
This method returns:
Poll::Pendingif the next directory entry is not yet available.Poll::Ready(Ok(Some(entry)))if the next directory entry is available.Poll::Ready(Ok(None))if there are no more directory entries in this stream.Poll::Ready(Err(err))if an IO error occurred while reading the next directory entry.
When the method returns Poll::Pending, the Waker in the provided
Context is scheduled to receive a wakeup when the next directory entry
becomes available on the underlying IO resource.
Note that on multiple calls to poll_next_entry, only the Waker from
the Context passed to the most recent call is scheduled to receive a
wakeup.

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;

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);
