}Expand description
The Referrer-Policy header: controls the value set by the browser for the Referer header.
Tells the browser if it should send all or part of URL of the current page to the next site the user navigates to via the Referer header. This can be important for security as the URL itself might expose sensitive data, such as a hidden file path or personal identifier.
Variants§
NoReferrer
Omits the Referer header (returned by Referrer::default()).
NoReferrerWhenDowngrade
Omits the Referer header on connection downgrade i.e. following HTTP
link from HTTPS site (Browser default).
Origin
Only send the origin of part of the URL, e.g. the origin of
https://foo.com/bob.html is https://foo.com.
OriginWhenCrossOrigin
Send full URL for same-origin requests, only send origin part when replying to cross-origin requests.
SameOrigin
Send full URL for same-origin requests only.
StrictOrigin
Only send origin part of URL, only send if protocol security level remains the same e.g. HTTPS to HTTPS.
StrictOriginWhenCrossOrigin
Send full URL for same-origin requests. For cross-origin requests, only send origin part of URL if protocol security level remains the same e.g. HTTPS to HTTPS.
UnsafeUrl
Send full URL for same-origin or cross-origin requests. This will leak the full URL of TLS protected resources to insecure origins. Use with caution.

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>

§Example

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};

§Example

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 underline(&self) -> 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);
