Struct SessionMeta 

#[non_exhaustive]
pub struct SessionMeta {
    pub id: String,
    pub title: String,
    pub created_at: DateTime<Utc>,
    pub updated_at: DateTime<Utc>,
    pub version: u32,
    pub sequence: u64,
}

Metadata stored as the first line of a session JSONL file.

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 session identifier.

title: String

Human-readable session title.

created_at: DateTime<Utc>

When the session was created.

updated_at: DateTime<Utc>

When the session was last updated.

version: u32

Schema version for migration support. Defaults to 1.

sequence: u64

Optimistic concurrency sequence number. Incremented on every write.

Implementations

impl SessionMeta

pub fn new( id: impl Into<String>, title: impl Into<String>, created_at: DateTime<Utc>, updated_at: DateTime<Utc>, ) -> Self

Creates a new session metadata record with the given identity and timestamps.

version defaults to 1 and sequence defaults to 0; use with_version / with_sequence to override either.

pub const fn with_version(self, version: u32) -> Self

Overrides the schema version (defaults to 1).

pub const fn with_sequence(self, sequence: u64) -> Self

Overrides the optimistic-concurrency sequence number (defaults to 0).
