Overview ¶
Package observability provides instance-owned contracts and adapters for Spice's dependency-free lifecycle, HTTP, and generated method observations.

Variables ¶
var ErrMethodPanicked = errors.New("observed method panicked")
ErrMethodPanicked identifies a method observation completed by a panic. Observe reports it and then re-panics with the original value.
Functions ¶
func NewSlogLifecycleObserver ¶
NewSlogLifecycleObserver constructs a structured lifecycle observer. Begin records use debug level; successful completion uses info and failures use error. Component and module values come from compiler-generated metadata.
func Observe ¶
func Observe( ctx context.Context, definition MethodDefinition, observers []MethodObserver, work MethodWork, ) (resultErr error)
Observe executes work once and reports completion to instance-owned observers. Observer contexts are composed in declaration order and completion callbacks run in reverse order. Panics are observed and re-raised.
Types ¶
type MethodDefinition ¶
MethodDefinition is compiler-owned metadata for one observed service method.
type MethodObserver ¶
type MethodObserver interface {
BeginMethod(context.Context, MethodDefinition) (context.Context, func(MethodResult))
}
MethodObserver begins one method observation on the calling goroutine. It may return a derived context and an optional completion callback.
type MethodResult ¶
type MethodResult struct {
Definition MethodDefinition
Duration time.Duration
Err error
Panicked bool
}
MethodResult describes one completed observed method invocation.
type MethodWork ¶
MethodWork is generated service-method logic executed within observation.
type SlogHTTPObserver ¶
type SlogHTTPObserver struct {
// contains filtered or unexported fields
}
SlogHTTPObserver writes one bounded, route-template-based completion record for each generated HTTP request. It never records raw URLs, headers, bodies, query values, or client-provided path values.
func NewSlogHTTPObserver ¶
func NewSlogHTTPObserver(logger *slog.Logger) (*SlogHTTPObserver, error)
NewSlogHTTPObserver constructs an instance-owned structured HTTP observer.
func (*SlogHTTPObserver) BeginHTTP ¶
func (observer *SlogHTTPObserver) BeginHTTP( ctx context.Context, route web.RouteMetadata, ) (context.Context, func(web.HTTPResult))
BeginHTTP implements web.HTTPObserver.
