StaticVerifierResolver

cratestack::cose

Struct StaticVerifierResolver 

Source 
pub struct StaticVerifierResolver { /* private fields */ }
Expand description

A fixed set of verification keys, indexed by their kid. For tests and for in-process use (a service that knows its peers’ keys at start-up). A device-key database or a published COSE_KeySet implements CoseVerifierResolver itself.

The kid is computed from each key, so a key can never be filed under a kid it does not have.

Implementations§

Source§

impl StaticVerifierResolver

Source

pub fn new() -> StaticVerifierResolver

An empty resolver: every kid is unknown until keys are added.

Source

pub fn with_key(self, key: CoseVerifyKey) -> StaticVerifierResolver

Add key. Keys that share a kid (an 8-byte prefix collision, or one HMAC secret listed for both HMAC algorithms) are all returned for it, in the order they were added.

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.

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();

§

fn quirk(&self, value: Quirk) -> Painted<&T>

Enables the yansi [Quirk] value.
