func (*Context[T]) StartArray added in v0.0.7

func (c *Context[T]) StartObject(o typed.Typed)

func (*Context[T]) SuspendArray added in v0.0.7 

func (c *Context[T]) SuspendArray() int

This is an advanced and very hacky thing. It's generally a "good thing" that this context is stateful. But in some cases, a caller might need more flexibility. This came up because within the process of validating an array, we needed to validate some other data which would not inherit the array index. This call erases the array state of the context. It returns this state (which is just the arrayDepth) to the caller, so that the caller can pass it back to ResumeArray when it's time to go back to the normal valiation

func (*Context[T]) Validate added in v0.0.7 

func (c *Context[T]) Validate(field *Field, value any, validator Validator[T]) (any, bool)

Directly executes a validator with the given value and for the given field. This is generally called when validation of fields is dynamic, often in a a Func callbac(like Object().Func) where the fields to validate are dependent on other parts of the data

type Field added in v0.0.5 

type Field struct {
	// The name of the actual field that we need to look up. This is
	// always equal to the last element in Path
	Name string

	// strings.Join(Path, ".")
	Flat string

	// The full path of the field.
	// Could be a single value, like: ["name"],
	// Could be nested, like ["user", "name"],
	// Could contain placeholders for array indexex, like: ["users", "", name]
	Path []string
}

	// contains filtered or unexported fields
}

func (*ObjectValidator[T]) Field added in v0.0.5 

func (v *ObjectValidator[T]) Field(name string, validator Validator[T]) *ObjectValidator[T]

ObjectValidator is the only validator that holds on to a Field (i.e. it's the only validator that knows what things are called). You'd think the field is just something like "name" or "password", but a field also contains the whole path for nested objects, like "user.name" and "user.password". So, when an ObjectValidator is nested in another ObjectValidator, we need to build up the field paths throughout the graph. While an ArrayValidator doesn't hold a Field directly, its validator can be an ObjectValidator (which does hold Fields), so we also have to inform the ArrayValidator about any nesting so that it can inform its validator (if that validator is an ObjectValidator)

func (v *ObjectValidator[T]) ValidateInput(input typed.Typed, ctx *Context[T]) bool

While Validate(raw, ctx) can be called on any validator, including this ObjectValidator, the ValidateInput is a speciality function meant to be called at the top level. (ValidateInput is really just a micro-optimization that skips some checks that we know we don't need at the top level, like a type check on the input)

	*concurrent.Pool[*Context[T]]
}
