Types

type Option

type Option func(*options)

Option sets an optional parameter of Table.

func WithExtraPaths

func WithExtraPaths(ps ...string) Option

WithExtraPaths returns option to add extra paths to UN/LOCODE tables in csv format.

type Prm

type Prm struct {
	// Path to UN/LOCODE csv table.

	// Path to csv table of UN/LOCODE Subdivisions.
	//
	// Must not be empty.
	SubDivPath string
}

Prm groups the required parameters of the Table's constructor.

All values must comply with the requirements imposed on them. Passing incorrect parameter values will result in constructor failure (error or panic depending on the implementation).

type Table

type Table struct {
	// contains filtered or unexported fields

func New

func New(prm Prm, opts ...Option) *Table

New creates a new instance of the Table.

Panics if at least one value of the parameters is invalid.

The created Table does not require additional initialization and is completely ready for work.

func (*Table) IterateAll

func (t *Table) IterateAll(f func(locode.Record) error) error

IterateAll scans table record one-by-one, parses UN/LOCODE record from it and passes it to f.

Returns f's errors directly.

func (*Table) SubDivName

func (t *Table) SubDivName(countryCode *locodedb.CountryCode, code string) (string, error)

SubDivName scans table record to in-memory table (once), and returns subdivision name on country and subdivision codes match.

Returns locodedb.ErrSubDivNotFound if no entry matches.
