Struct LiveCheckpoint 

pub struct LiveCheckpoint {
    pub schema: String,
    pub bindings: CheckpointBindings,
    pub items: Vec<CheckpointItem>,
}

Fields

schema: String

bindings: CheckpointBindings

items: Vec<CheckpointItem>

Implementations

impl LiveCheckpoint

pub fn check(&self) -> Result<(), LiveError>

pub fn read( path: impl AsRef<Path>, expected: &CheckpointBindings, ) -> Result<Self, LiveError>

Compare all bindings before the caller opens any spend journal.

pub fn write_atomic(&self, path: impl AsRef<Path>) -> Result<(), LiveError>

Replace atomically on the same filesystem, then persist the directory entry. A failed write before rename preserves the previous checkpoint.

Trait Implementations

impl Clone for LiveCheckpoint

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LiveCheckpoint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LiveCheckpoint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Document for LiveCheckpoint

const SCHEMA: &'static str = "rustev.live-checkpoint/1"

The schema string this document carries (spec 002, 3.2.1).

const LIMITS: ParseLimits = REPLAY_V1

The limit set its bytes are scanned against (spec 002, 3.2.5).

fn schema(&self) -> &str

The value of the document’s own schema field.

fn parse(bytes: &[u8]) -> Result<Self, DocumentError>

Scan, deserialize and check the schema string.

fn canonical(&self) -> Result<Vec<u8>, CanonicalError>

The canonical bytes (spec 002, 3.3.1).

fn record_canonical(&self) -> Result<Vec<u8>, CanonicalError>

where Self: PartialEq,

The record canonical bytes (spec 004, 5.6): the canonical bytes, with finite fractional numbers written in shortest round-trip form.

fn record_digest(&self) -> Result<ContentDigest, CanonicalError>

where Self: PartialEq,

sha256(SCHEMA || 0x00 || record canonical bytes) (spec 004, 3.1.6). Equal to the identity of an identified document.

impl Eq for LiveCheckpoint

impl PartialEq for LiveCheckpoint

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for LiveCheckpoint

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
