minimum exceeds maximum

Error message

minimum exceeds maximum

What it means

When both `minimum` and `maximum` numeric bounds are declared in a schema tag, the minimum must not exceed the maximum. An inverted range can never be satisfied, so parseSchemaTag rejects the tag at compile time.

Solutions

  1. Ensure minimum <= maximum in the tag.
  2. Swap the two values if inverted.
  3. Remove the redundant bound if only one limit is meaningful.

Example fix

// before
Amount float64 `schema:"required;minimum=100;maximum=10"`
// after
Amount float64 `schema:"required;minimum=10;maximum=100"`
Defensive patterns

Strategy: validation

Validate before calling

func numericRangeOK(min, max *float64) bool {
	return min == nil || max == nil || *min <= *max
}

Prevention

When it happens

Trigger: A tag like schema:"optional;minimum=100;maximum=10" on a numeric input field.

Common situations: Transcribing bounds in the wrong order, changing one bound after a requirements change, or copying bounds from an inverted spec.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
