pub struct Entry<'p, K: AsKey, V: DeserializeOwned + Serialize> { /* private fields */ }Expand description
Accessor for an entry, embeds an open file handle, allows to load or lock-and-delete etc.
Implementations§
Source§impl<'p, K: AsKey, V: DeserializeOwned + Serialize> Entry<'p, K, V>
impl<'p, K: AsKey, V: DeserializeOwned + Serialize> Entry<'p, K, V>
pub fn target_path(&self) -> &Path
pub fn file_name(&self) -> &OsStr
Sourcepub fn key(&self) -> Result<K, KeyValError>
pub fn key(&self) -> Result<K, KeyValError>
Can return file name decoding errors for files that were inserted into the directory via other means than this library.
pub fn get(&mut self) -> Result<V, KeyValError>
Sourcepub fn take_lockable_file(&mut self) -> Option<LockableFile<File>>
pub fn take_lockable_file(&mut self) -> Option<LockableFile<File>>
Giving up the Entry accessor, means you have to call get
first. (Yes, locking wouldn’t protect that anyway! This lock
is not for that!) Returns None if already taken.
Sourcepub fn exists(&mut self) -> bool
pub fn exists(&mut self) -> bool
Whether the entry currently (still) exists – XX But there is no guarantee it is still the old one!
Sourcepub fn delete(&self) -> Result<bool, KeyValError>
pub fn delete(&self) -> Result<bool, KeyValError>
Returns whether a file deletion actually happened (concurrent
deletes might already have removed it). XX Same caveat as with
exists.

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().

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>
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);
