Functions

func DecodeEWKB added in v1.1.41 

func DecodeEWKB(raw []byte) (geojson []byte, srid int, err error)

DecodeEWKB decodes raw PostGIS EWKB bytes into a GeoJSON geometry object and its SRID.

func DecodeEWKBHex added in v1.1.41 

func DecodeEWKBHex(s string) (geojson []byte, srid int, err error)

DecodeEWKBHex decodes a PostGIS hex-EWKB string (the default text representation of a geometry column) into a GeoJSON geometry object and its SRID. An SRID of 0 means "unspecified".

func GeoJSONToWKT added in v1.1.41 

func GeoJSONToWKT(geojson []byte) (string, error)

GeoJSONToWKT converts a GeoJSON geometry object to its WKT representation.

func IsJSONType added in v1.1.44 

func IsJSONType(t reflect.Type) bool

IsJSONType reports whether t is a spectypes JSON/JSONB wrapper.

func IsSpatialType added in v1.1.41 

func IsSpatialType(t reflect.Type) bool

IsSpatialType reports whether t is a PostGIS geometry/geography wrapper.

func IsVectorType added in v1.1.41 

func IsVectorType(t reflect.Type) bool

IsVectorType reports whether t is a pgvector wrapper (vector/halfvec/sparsevec).

func SQLTypeName added in v1.1.41 

func SQLTypeName(t reflect.Type) (string, bool)

SQLTypeName returns the canonical PostgreSQL type name for a spectypes wrapper type, or ("", false) if t is not a recognised spectypes type.

func ToJSONDT 

func ToJSONDT(dt time.Time) string

ToJSONDT formats a time.Time to RFC3339 string.

func TryIfInt64 

func TryIfInt64(v any, def int64) int64

TryIfInt64 tries to parse any value to int64 with default.

func UnwrapKind added in v1.1.45 

func UnwrapKind(t reflect.Type) reflect.Kind

UnwrapKind returns the reflect.Kind to use when reasoning about a column's comparability (numeric vs. string vs. other) for filter building. Plain Go types return their own Kind unchanged. spectypes.SqlNull[T] wrappers (and types that embed one, such as SqlTimeStamp/SqlDate/SqlTime) always report reflect.Struct for their own Kind even when T is an int64 or string, which would otherwise make numeric/text columns look "complex" and force an unnecessary CAST(... AS TEXT) that defeats native column indexes. For those wrappers, UnwrapKind returns the Kind of the wrapped value T instead.

Types

type CIString added in v1.1.53 

type CIString string

CIString is a string that stores, scans, and returns its value exactly as given (no case normalization), but compares case-insensitively via Equal and EqualString. Use it as a bun model field type for columns (e.g. citext, or codes matched case-insensitively) where you want Go-side case-insensitive comparisons without forcing the stored/returned value to a particular case.

func (CIString) Compare added in v1.1.53 

func (s CIString) Compare(other CIString) int

Compare returns -1, 0, or +1 if s is less than, equal to, or greater than other, ignoring case. Useful with slices.SortFunc or similar.

func (CIString) Equal added in v1.1.53 

func (s CIString) Equal(other CIString) bool

Equal reports whether s and other are equal, ignoring case.

func (CIString) EqualString added in v1.1.53 

func (s CIString) EqualString(other string) bool

EqualString reports whether s equals other, ignoring case.

func (CIString) Less added in v1.1.53 

func (s CIString) Less(other CIString) bool

Less reports whether s sorts before other, ignoring case. Suitable for sort.Slice or slices.SortFunc comparisons.

func (*CIString) Scan added in v1.1.53 

func (s *CIString) Scan(value any) error

Scan implements sql.Scanner. The value is stored unchanged.

func (CIString) String added in v1.1.53 

func (s CIString) String() string

String implements fmt.Stringer.

func (CIString) Value added in v1.1.53 

func (s CIString) Value() (driver.Value, error)

Value implements driver.Valuer. The value is passed through unchanged.

type LCString added in v1.1.53 

type LCString string

LCString is a string that always stores, scans, and returns as lowercase. Use it as a bun model field type for columns that must be normalized to lowercase (e.g. codes, slugs, emails) rather than merely compared case-insensitively; see CIString if the original case must be preserved.

func (LCString) Equal added in v1.1.53 

func (s LCString) Equal(other LCString) bool

Equal reports whether s and other are equal (case-insensitively, since both normalize to lowercase).

EqualString reports whether s equals other, ignoring case.

func (LCString) MarshalJSON added in v1.1.53 

func (s LCString) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler, always lowercase. Needed because encoding/json marshals a bare string-kind type as-is and does not call Value/String, so a value constructed directly (not scanned from the DB) would otherwise serialize with its original case.

func (*LCString) Scan added in v1.1.53 

func (s *LCString) Scan(value any) error

Scan implements sql.Scanner, always lowercase.

func (LCString) String added in v1.1.53

type SqlGeometry struct {

SqlGeometry is a nullable PostGIS `geometry` column.

On Scan it accepts the PostGIS default hex-EWKB text output, a raw GeoJSON object, or a WKT/EWKT string (e.g. when the column is selected via ST_AsGeoJSON / ST_AsText). Internally it holds a canonical GeoJSON geometry object plus the SRID.

On Value it emits `SRID=<n>;<WKT>` text. PostGIS registers an implicit text -> geometry cast, so parameterised inserts/updates work without wrapping the placeholder in a constructor function.

MarshalJSON emits the GeoJSON geometry object (or null).
