Struct Checkpoint 

pub struct Checkpoint {
    pub origin: LogOrigin,
    pub size: u64,
    pub root: MerkleHash,
    pub timestamp: DateTime<Utc>,
}

An unsigned transparency log checkpoint.

Args:

• origin — Log origin string (e.g., “auths.dev/log”).
• size — Number of entries in the log at this checkpoint.
• root — Merkle root hash of the log at this size.
• timestamp — When the checkpoint was created.

Usage:

let cp = Checkpoint {
    origin: LogOrigin::new("auths.dev/log")?,
    size: 42,
    root: merkle_root,
    timestamp: Utc::now(),
};

Fields

origin: LogOrigin

size: u64

root: MerkleHash

timestamp: DateTime<Utc>

Implementations

impl Checkpoint

pub fn to_note_body(&self) -> String

Serialize to the C2SP checkpoint body format (three lines: origin, size, base64 hash).

pub fn from_note_body( body: &str, timestamp: DateTime<Utc>, ) -> Result<Self, TransparencyError>

Parse from C2SP checkpoint body lines.

Trait Implementations

impl Clone for Checkpoint

fn clone(&self) -> Checkpoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Checkpoint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Checkpoint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Checkpoint

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

impl Serialize for Checkpoint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
