pub struct Authenticator { /* private fields */ }Expand description
Turns an Authorization header into a Principal, or into nothing.
Nothing is the default: a caller with no credential is a principal only
when the deployment configured an anonymous client and opted in with
allow_anonymous. Two switches, because one of them is the kind that
gets flipped in a hurry.
Implementations§
Source§impl Authenticator
impl Authenticator
Sourcepub fn new(
clients: impl IntoIterator<Item = (Token, Principal)>,
anonymous: Option<Principal>,
) -> Self
pub fn new( clients: impl IntoIterator<Item = (Token, Principal)>, anonymous: Option<Principal>, ) -> Self
An authenticator over clients, with an optional anonymous
principal for callers that present no credential.
Sourcepub fn allows_anonymous(&self) -> bool
pub fn allows_anonymous(&self) -> bool
Whether an unauthenticated caller is somebody here.
Sourcepub fn authenticate(&self, authorization: Option<&str>) -> Option<Principal>
pub fn authenticate(&self, authorization: Option<&str>) -> Option<Principal>
Who is calling, given the raw Authorization header.
Three answers, and the middle one is the one worth stating: a header that is present but unusable — a wrong scheme, an unknown token — is not downgraded to anonymous. A caller that presented a credential meant to present that credential, and silently serving it the anonymous grants instead is how an expired token becomes a deployment that appears to work.

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>
renamed to 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);
