Enum SourceCheckInstruction 

pub enum SourceCheckInstruction {
    Field(FieldSourceKey),
    Literal(ScalarLiteral),
    Equal,
    NotEqual,
    LessThan,
    LessThanOrEqual,
    GreaterThan,
    GreaterThanOrEqual,
    And,
    Or,
    Not,
    IsNull,
    IsNotNull,
    Length,
}

One instruction in a bounded source-level postfix check expression.

This is an AST transport, not accepted bytecode: field references remain typed current-name keys and IcyDB still owns accepted binding and compilation.

Variants

Field(FieldSourceKey)

Push one field value.

Literal(ScalarLiteral)

Push one admitted proposal literal.

Equal

SQL equality.

NotEqual

SQL inequality.

LessThan

SQL less-than.

LessThanOrEqual

SQL less-than-or-equal.

GreaterThan

SQL greater-than.

GreaterThanOrEqual

SQL greater-than-or-equal.

And

SQL three-valued conjunction.

Or

SQL three-valued disjunction.

Not

SQL three-valued negation.

IsNull

Two-valued null test.

IsNotNull

Two-valued non-null test.

Length

Bounded scalar/collection length.
