var ErrBraceMismatch = errors.New("wkt: brace mismatch")

ErrBraceMismatch is returned when braces do not match.

Functions ¶

func Marshal ¶

func Marshal(g geom.T, applyOptFns ...EncodeOption) (string, error)

Marshal translates a geometry to the corresponding WKT.

func Unmarshal ¶ added in v1.1.0

func Unmarshal(wkt string) (geom.T, error)

Unmarshal translates a WKT to the corresponding geometry.

Types ¶

type EncodeOption ¶ added in v1.2.0

type EncodeOption func(*Encoder)

An EncodeOption is an encoder option.

func EncodeOptionWithMaxDecimalDigits ¶ added in v1.2.0

func EncodeOptionWithMaxDecimalDigits(maxDecimalDigits int) EncodeOption

EncodeOptionWithMaxDecimalDigits sets the maximum decimal digits to encode.

type Encoder ¶ added in v1.2.0

type Encoder struct {
	// contains filtered or unexported fields
}

Encoder encodes WKT based on specified parameters.

func NewEncoder ¶ added in v1.2.0

func NewEncoder(applyOptFns ...EncodeOption) *Encoder

NewEncoder returns a new encoder with the given options set.

func (*Encoder) Encode ¶ added in v1.2.0

func (e *Encoder) Encode(g geom.T) (string, error)

Encode translates a geometry to the corresponding WKT.

type SyntaxError ¶ added in v1.4.0

type SyntaxError struct {
	// contains filtered or unexported fields
}

SyntaxError is an error that occurs during parsing of a WKT string.

func (*SyntaxError) Error ¶ added in v1.4.0

func (e *SyntaxError) Error() string

Error generates a detailed syntax error message with line and pos numbers as well as a snippet of the erroneous input.
