Struct ReadReply 

#[non_exhaustive]
pub struct ReadReply {
    pub rows: Vec<StepRow>,
    pub next: Option<Cursor>,
    pub through: Cursor,
}

Reply of usage.steps.read. Unknown members are ignored.

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.

rows: Vec<StepRow>

Oldest first. Several rows may share an identity; the last one wins.

next: Option<Cursor>

The cursor to pass as after for the following page, or null when this reply reached through. Always sent, as null when absent.

through: Cursor

The newest committed cursor.

Implementations

impl ReadReply

pub fn new( rows: Vec<StepRow>, next: Option<Cursor>, through: impl Into<Cursor>, ) -> Self

pub fn resume_after(&self) -> &Cursor

The cursor the next read passes as after: next while more pages remain, otherwise through.

pub fn check_closed(value: &Value) -> Result<(), NotClosed>

Reports a reply member, or a member of any row, outside the published v1 lists. For the provider’s own tests: whatever it emits must stay within the published lists. Readers ignore unknown members instead.
