The P4 operand of a VDBE instruction.

P4 is a polymorphic operand that can hold different types depending on the opcode.

Variants

None

No P4 value.

Int(i32)

A 32-bit integer value.

Int64(i64)

A 64-bit integer value.

Real(f64)

A 64-bit float value.

Str(String)

A string value.

Blob(Vec<u8>)

A blob value.

Collation(String)

A collation sequence name.

FuncName(String)

A function name (for Function/PureFunc opcodes).

FuncNameCollated(String, String)

A function name with an associated collation sequence for DISTINCT deduplication in aggregate functions (e.g. COUNT(DISTINCT col) where col has COLLATE NOCASE).

Table(String)

A table name.

Index(String)

An index name (for IdxInsert/IdxDelete opcodes).

Affinity(String)

An affinity string (one char per column).

TimeTravelCommitSeq(u64)

Time-travel target: commit sequence for FOR SYSTEM_TIME AS OF COMMITSEQ <n>.

TimeTravelTimestamp(String)

Time-travel target: ISO-8601 timestamp for FOR SYSTEM_TIME AS OF '<ts>'.

Trait Implementations

impl Clone for P4

fn clone(&self) -> P4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for P4

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

Formats the value using the given formatter.

impl PartialEq for P4

fn eq(&self, other: &P4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
