v2.0.0

Compare Source

v2.0 keeps breaking changes intentionally minimal (5 items). Core API,
validator names, tag semantics and the DataFace interface are unchanged — most
projects upgrade by bumping the import path to /v2. See
docs/UPGRADE-v2.md for the full migration guide.

Breaking Changes

• Module path github.com/gookit/validate → github.com/gookit/validate/v2
  (per Go Modules semantic import versioning). Update both go get and all
  import lines.
• Minimum Go version 1.19 → 1.21 (go.mod).
• Between signature Between(val any, min, max int64) →
  Between(val, min, max any), now consistent with Gt/Lt via valueCompare
  (supports int / uint / float / string). Semantic change for fractional bounds:
  Between(2.9, 1, 2) was true (int64 truncation) and is now false (no more
  truncation). Tag/StringRule usage like between:1,2 is unaffected.
• Removed deprecated ValueLen(v) — use goutil's reflects.Len(v) instead.
• Sub-struct cascade now requires the parent field to carry a validate tag.
  Previously a sub-struct field (struct / *struct / slice-of-struct /
  map-of-struct) was always descended into to collect its inner rules. Now
  (CheckSubOnParentMarked defaults to true) cascade only happens when the
  parent field has a validate tag — the value may be empty (validate:""
  is enough to mark it); a named field with no validate tag is no
  longer descended into (Java @Valid-style opt-in). Anonymous embedded
  structs (e.g. type Bar struct { Foo }) are exempt — they are part of
  the parent and always cascade regardless of tag; only named sub-struct
  fields require the tag. To restore the v1 "always cascade" behavior globally:
  validate.Config(func(o *validate.GlobalOption){ o.CheckSubOnParentMarked = false }).
  See docs/UPGRADE-v2.md for migration details.

Note: the DataFace interface is unchanged (a redesign was planned during
v2.0 but rejected after profiling); custom DataFace implementers are unaffected.

New Features

• AddCustomType(fn CustomTypeFunc, types ...any) — register an underlying
  value extractor for custom/wrapped types (e.g. sql.NullString, money types).
  The extracted value flows through the existing validation paths (required /
  numeric compare / length / string rules). CustomTypeFunc func(field reflect.Value) any; returning nil is treated as empty. Mirrors
  go-playground/validator's RegisterCustomTypeFunc. ResetCustomTypes() clears
  the registry. Zero overhead on the hot path when nothing is registered (atomic
  gate short-circuit).
• NewFactory() + Factory.Struct / Factory.Map + (*Validation).Release()
  — opt-in pooled factory that reuses *Validation instances across many
  same-type validations, amortizing construction cost (allocs roughly halved in
  reuse scenarios). Non-default: Struct / Map / New behavior and lifecycle
  are unchanged.

Performance

Measured on Go 1.25 (count=6) against the v1.6.0 final:

Benchmark	v1.6.0	v2.0 default
StructFlat	2295 ns / 34 allocs	1870 ns / 23 allocs (-18% / -32%)
StructNested	2137 ns / 34 allocs	1722 ns / 24 allocs (-19% / -29%)
MapValidate	3314 ns / 72 allocs	3350 ns / 72 allocs (flat)
ValValue	725 ns / 11 allocs	737 ns / 11 allocs (flat)
SliceOfStruct	—	10900 ns / 208 allocs (dynamic, flat)
FactoryStructReuse (new)	—	1633 ns / 11 allocs (-52% allocs vs non-factory)

Coverage 95.7% (v1.6.0 was 95.6%).

Internal

• Pre-convert rule args at build time (drop the runtime convertArgsType).
• Share immutable static template rules instead of cloning per instance.
• Fix string validators panicking on non-string fields.
• Split validators.go by category (compare / string / type files).
• Sink pure-reflect helpers and fieldValue into internal/ (reflectx,
  fieldval).
