Struct ResultLimits 

pub struct ResultLimits {
    pub max_rows: Option<u64>,
    pub max_bytes: Option<u64>,
    pub max_candidate_count: Option<u64>,
}

Per-request result bounds (spec sections 4.9 and 10.4, S1D-001).

Every request is bounded: None does NOT mean unbounded, it means the server applies its configured default (see the DEFAULT_* constants for the conservative shipped defaults) and may clamp explicit values down to configured ceilings. The effective limits are what the executor enforces; exceeding them fails the request with mongreldb_types::errors::ErrorCategory::ResourceExhausted.

Fields

max_rows: Option<u64>

Maximum result rows; None applies the server default.

max_bytes: Option<u64>

Maximum result bytes; None applies the server default.

max_candidate_count: Option<u64>

Maximum candidate rows scanned during retrieval; None applies the server default.

Implementations

impl ResultLimits

pub fn effective_max_rows(&self) -> u64

pub fn effective_max_bytes(&self) -> u64

Effective byte bound after applying server-enforceable defaults.

pub fn effective_max_candidate_count(&self) -> u64

Effective candidate-count bound after applying server-enforceable defaults.
