Implementations§
Source§impl HttpHeaders
impl HttpHeaders
Sourcepub fn get(&self, name: &str) -> Option<HeaderValue>
pub fn get(&self, name: &str) -> Option<HeaderValue>
Get the value associated with the given name. If there are multiple values associated with
the name, then the first one is returned. Use get_all to get all values associated with
a given name. Returns None if there are no values associated with the name.
Sourcepub fn get_all(&self, name: &str) -> impl Iterator<Item = HeaderValue>
pub fn get_all(&self, name: &str) -> impl Iterator<Item = HeaderValue>
Get all of the values corresponding to a name. If the name is not present, an empty list is returned. However, if the name is present but empty, this is represented by a list with one or more empty values present.
Sourcepub fn has(&self, name: &str) -> bool
pub fn has(&self, name: &str) -> bool
Returns true if the map contains a value for the specified name.
Sourcepub fn set(
&mut self,
name: impl Into<HeaderName>,
values: impl Iterator<Item: Into<HeaderValue>>,
)
pub fn set( &mut self, name: impl Into<HeaderName>, values: impl Iterator<Item: Into<HeaderValue>>, )
Set all of the values for a name. Clears any existing values for that name, if they have been set.
Sourcepub fn remove(&mut self, name: &str) -> Option<HeaderValue>
pub fn remove(&mut self, name: &str) -> Option<HeaderValue>
Removes a name from the map, returning the value associated with the name. Returns None if the map does not contain the name. If there are multiple values associated with the name, then the first one is returned.
Sourcepub fn append(
&mut self,
name: impl Into<HeaderName>,
value: impl Into<HeaderValue>,
)
pub fn append( &mut self, name: impl Into<HeaderName>, value: impl Into<HeaderValue>, )
Append a value for a name. Does not change or delete any existing values for that name.
Sourcepub fn iter(&self) -> impl Iterator<Item = (HeaderName, HeaderValue)>
pub fn iter(&self) -> impl Iterator<Item = (HeaderName, HeaderValue)>
An iterator visiting all name-value pairs. The iteration order is arbitrary, but consistent across platforms for the same crate version. Each name will be yielded once per associated value. So, if a name has 3 associated values, it will be yielded 3 times.

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);
