Overview ¶

Package criteria validates client predicates using the SQL parser's AST and emits only approved columns, operators, and bound values.

Index ¶

type Column
type Compiler
- func (c *Compiler) Compile(source string, placeholders []any) (string, []any, error)
- func (c *Compiler) CompileWithColumns(source string, placeholders []any) (string, []any, []Column, error)
type Method
- func (m *Method) Validate() error

Types ¶

type Column ¶

type Column struct {
	Expression string
	Type       reflect.Type
	TimeLayout string
}

type Compiler ¶

type Compiler struct {
	Columns map[string]Column
	Methods map[string]Method
}

Compiler carries the immutable set of names allowed by view selector policy. Values map client names to trusted SQL column expressions.

func (*Compiler) Compile ¶

func (c *Compiler) Compile(source string, placeholders []any) (string, []any, error)

func (*Compiler) CompileWithColumns ¶

func (c *Compiler) CompileWithColumns(source string, placeholders []any) (string, []any, []Column, error)

CompileWithColumns also reports the trusted columns referenced by this invocation, including column comparisons on the right-hand side.

type Method ¶

type Method struct {
	Name string
	Args []reflect.Type
}

func (*Method) Validate ¶

func (m *Method) Validate() error

Validate canonicalizes an authored function name through the SQL parser. Only one function identity is accepted; argument or statement text cannot become part of the configured SQL emitted for a client method call.
