ReadFlags

Struct ReadFlags 

Source
pub struct ReadFlags(/* private fields */);
Expand description

Read-result flag bitset per read-protocol.md § 5 / § 6.

Bits reserved but not issued in v1 (part of the stable on-wire layout, always clear): bit 1 (was CONFLICT), bit 5 (was CROSS_WORKSPACE), bit 6 (was CONTESTED). See spec note.

Implementations§

Source§

impl ReadFlags

Source

pub const STALE_SYMBOL: u32

At least one kept record references a retired symbol.

Source

pub const LOW_CONFIDENCE: u32

At least one kept record’s confidence is below the query’s :confidence_threshold (default 0.5).

Source

pub const PROJECTED_PRESENT: u32

At least one kept record has flags.projected.

Source

pub const TRUNCATED: u32

The result was capped by :limit before exhausting all matches.

Source

pub const EXPLAIN_FILTERED_ACTIVE: u32

:explain_filtered is active for this query; filtered may be non-empty.

Source

pub const fn empty() -> Self

Construct an empty flag set.

Source

pub const fn contains(self, bits: u32) -> bool

true if any of bits is set.

Source

pub const fn with(self, bits: u32) -> Self

Set bits, returning the new flags.

Source

pub const fn bits(self) -> u32

Raw u32 view — for interop with e.g. wire serialization.
