Struct Announcement

pub struct Announcement {
    pub node: NodeId,
    pub signature: Signature,
    pub message: AnnouncementMessage,
}

Fields

node: NodeId

Node identifier.

signature: Signature

Signature over the announcement.

message: AnnouncementMessage

Unsigned node announcement.

Implementations

impl Announcement

pub const POW_PARAMS: (u8, u32, u32)

Proof-of-work parameters for announcements.

These parameters are fed into scrypt. They represent the log2(N), r, p parameters, respectively.

• log2(N) – iterations count (affects memory and CPU usage), e.g. 15
• r – block size (affects memory and CPU usage), e.g. 8
• p – parallelism factor (threads to run in parallel - affects the memory, CPU usage), usually 1

15, 8, 1 are usually the recommended parameters.

pub const POW_SALT: &'static [u8] = b"rad"

Salt used for generating PoW.

pub fn verify(&self) -> bool

Verify this announcement’s signature.

pub fn matches(&self, filter: &Filter) -> bool

pub fn variant_eq(&self, other: &Self) -> bool

Check whether this announcement is of the same variant as another.

pub fn timestamp(&self) -> Timestamp

Get the announcement timestamp.

Trait Implementations

impl Clone for Announcement

fn clone(&self) -> Announcement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Announcement

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

Formats the value using the given formatter.

impl From<Announcement> for Message

fn from(ann: Announcement) -> Self

Converts to this type from the input type.

impl PartialEq for Announcement

fn eq(&self, other: &Announcement) -> 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.
