Signable is a generic interface for any kind of object that can be cryptographically signed.

Like signing_result, the signable interface presents

(1) Properties - A set of key-value pairs (2) Property Lists - A set of named key-value pair lists

as well as

(3) A message payload modeled as a stream

When creating a signable “subclass” the query interface should map to retrieving the properties of the underlying object needed by signing algorithms that can operate on it.

As an example, if a signable implementation wrapped an http request, you would query request elements like method and uri from the property interface, headers would be queried via the property list interface, and the request body would map to the payload stream.

String constants that map to agreed on keys for particular signable types (“METHOD”, “URI”, “HEADERS”, etc…) are exposed in appropriate header files.

Trait Implementations

impl Clone for aws_signable

fn clone(&self) -> aws_signable

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for aws_signable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for aws_signable

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<aws_signable> for aws_signable

fn eq(&self, other: &aws_signable) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
