Struct Snapshot 

#[non_exhaustive]
pub struct Snapshot {
    pub schema_version: u32,
    pub id: SnapshotId,
    pub namespace_id: Option<NamespaceId>,
    pub root_hash: Hash,
    pub created_at: u64,
    pub description: Option<String>,
    pub total_size: u64,
    pub file_count: u64,
    pub entries: Vec<SnapshotEntry>,
}

A content-addressed snapshot of a folder or local directory.

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.

schema_version: u32

id: SnapshotId

namespace_id: Option<NamespaceId>

root_hash: Hash

created_at: u64

description: Option<String>

total_size: u64

file_count: u64

entries: Vec<SnapshotEntry>

Implementations

impl Snapshot

pub fn new( namespace_id: Option<NamespaceId>, entries: Vec<SnapshotEntry>, description: Option<String>, ) -> Self

Build a snapshot from already-addressed content references.

No file data is copied by this operation.

pub fn validate(&self) -> Result<()>

Validate the snapshot schema, paths, counts, and content root.

Errors

Returns an error if any snapshot invariant is violated.

pub fn to_bytes(&self) -> Result<Vec<u8>>

Serialize a validated snapshot manifest.

Errors

Returns an error if validation or serialization fails.

pub fn from_bytes(bytes: impl AsRef<[u8]>) -> Result<Self>

Decode and validate a snapshot manifest.

Errors

Returns an error if decoding or validation fails.

pub fn diff(&self, other: &Self) -> Result<SnapshotDiff>

Compare two snapshots by logical path and content hash.

Errors

Returns an error if either snapshot is invalid.

Trait Implementations

impl Clone for Snapshot

fn clone(&self) -> Snapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Snapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Snapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Snapshot

impl PartialEq for Snapshot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
