var (
ErrParse = errors.New("failed to parse the log query")
ErrPipeline = errors.New("failed execute pipeline")
ErrLimit = errors.New("limit reached while evaluating the query")
ErrIntervalLimit = errors.New("[interval] value exceeds limit")
ErrBlocked = errors.New("query blocked by policy")
ErrParseMatchers = errors.New("only label matchers are supported")
ErrUnsupportedSyntaxForInstantQuery = errors.New("log queries are not supported as an instant query type, please change your query to a range query type")
ErrorLabel = "__error__"
PreserveErrorLabel = "__preserve_error__"
ErrorDetailsLabel = "__error_details__"
)
Those errors are useful for comparing error returned by the engine. e.g. errors.Is(err,logqlmodel.ErrParse) let you know if this is a ast parsing error.

Types ¶
type LimitError ¶
type LimitError struct {
// contains filtered or unexported fields
}
func NewSeriesLimitError ¶
func NewSeriesLimitError(limit int) *LimitError
type ParseError ¶
type ParseError struct {
// contains filtered or unexported fields
}
ParseError is what is returned when we failed to parse.
func NewParseError ¶
func NewParseError(msg string, line, col int) ParseError
func NewStageError ¶
func NewStageError(expr string, err error) ParseError
type PipelineError ¶
type PipelineError struct {
// contains filtered or unexported fields
}
func NewPipelineErr ¶
func NewPipelineErr(metric labels.Labels) *PipelineError
type Result ¶
type Result struct {
Data parser.Value
Statistics stats.Result
Headers []*definitions.PrometheusResponseHeader
Warnings []string
