Struct CheckpointMeta 

#[non_exhaustive]
pub struct CheckpointMeta {
    pub id: String,
    pub thread_id: String,
    pub created_at: SystemTime,
    pub step: u32,
    pub parent_id: Option<String>,
}

Metadata about a single checkpoint.

Fields may be added in future versions — construct via CheckpointMeta::new.

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.

id: String

Unique checkpoint identifier.

thread_id: String

Thread this checkpoint belongs to.

created_at: SystemTime

When this checkpoint was created.

step: u32

Which superstep this was taken at.

parent_id: Option<String>

The checkpoint this one was derived from (lineage tracking). None for the first checkpoint in a thread.

Implementations

impl CheckpointMeta

pub fn new( id: impl Into<String>, thread_id: impl Into<String>, step: u32, ) -> Self

Create a new checkpoint metadata record.

The parent_id defaults to None. Use with_parent to set lineage.

pub fn with_parent(self, parent_id: impl Into<String>) -> Self

Set the parent checkpoint ID (the checkpoint this one was derived from).

Trait Implementations

impl Clone for CheckpointMeta

fn clone(&self) -> CheckpointMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointMeta

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

Formats the value using the given formatter.
