Struct PublicKeyDiscoveryInput 

#[non_exhaustive]
pub struct PublicKeyDiscoveryInput {
    pub recipient_static_private_key: Option<Blob>,
}

Inputs for creating a PublicKeyDiscovery Configuration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

recipient_static_private_key: Option<Blob>

The sender’s private key. MUST be PEM encoded.

Implementations

impl PublicKeyDiscoveryInput

pub fn recipient_static_private_key(&self) -> &Option<Blob>

The sender’s private key. MUST be PEM encoded.

impl PublicKeyDiscoveryInput

pub fn builder() -> PublicKeyDiscoveryInputBuilder

Creates a new builder-style object to manufacture PublicKeyDiscoveryInput.

Trait Implementations

impl Clone for PublicKeyDiscoveryInput

fn clone(&self) -> PublicKeyDiscoveryInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKeyDiscoveryInput

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

Formats the value using the given formatter.

impl PartialEq for PublicKeyDiscoveryInput

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

Tests for self and other values to be equal, and is used by ==.

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

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