Functions

func FileExists 

func FileExists(filePath string) (bool, error)

FileExists reports whether the named file or directory exists.

func NormalizeAddress 

func NormalizeAddress(addr string, defaultPort string) (hostport string, err error)

NormalizeAddress returns the normalized form of the address, adding a default port if necessary. An error is returned if the address, even without a port, is not valid.

func NormalizeAddresses 

func NormalizeAddresses(addrs []string, defaultPort string) ([]string, error)

NormalizeAddresses returns a new slice with all the passed peer addresses normalized with the given default port, and all duplicates removed.

Types

type AddressFlag added in v1.0.8 

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

AddressFlag contains a dcrutil.Address and implements the flags.Marshaler and Unmarshaler interfaces so it can be used as a config struct field.

func NewAddressFlag added in v1.0.8 

func NewAddressFlag() *AddressFlag

NewAddressFlag creates an AddressFlag with a default dcrutil.Address.

func (*AddressFlag) Address added in v1.6.0 

func (a *AddressFlag) Address(params dcrutil.AddressParams) (dcrutil.Address, error)

Address decodes the address flag for the network described by params. If the flag is the empty string, this returns a nil address.

func (*AddressFlag) MarshalFlag added in v1.0.8 

func (a *AddressFlag) MarshalFlag() (string, error)

MarshalFlag satisfies the flags.Marshaler interface.

func (*AddressFlag) UnmarshalFlag added in v1.0.8 

func (a *AddressFlag) UnmarshalFlag(addr string) error

UnmarshalFlag satisfies the flags.Unmarshaler interface.

type AmountFlag added in v0.1.0 

type AmountFlag struct {
	dcrutil.Amount
}

AmountFlag embeds a dcrutil.Amount and implements the flags.Marshaler and Unmarshaler interfaces so it can be used as a config struct field.

func NewAmountFlag added in v0.1.3 

func NewAmountFlag(defaultValue dcrutil.Amount) *AmountFlag

NewAmountFlag creates an AmountFlag with a default dcrutil.Amount.

func (*AmountFlag) MarshalFlag added in v0.1.0 

func (a *AmountFlag) MarshalFlag() (string, error)

MarshalFlag satisfies the flags.Marshaler interface.

func (*AmountFlag) UnmarshalFlag added in v0.1.0 

func (a *AmountFlag) UnmarshalFlag(value string) error

UnmarshalFlag satisfies the flags.Unmarshaler interface.

type CurveFlag added in v0.7.0 

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

CurveFlag describes a curve and implements the flags.Marshaler and Unmarshaler interfaces so it can be used as a config struct field.

func NewCurveFlag added in v0.7.0 

func NewCurveFlag(defaultValue CurveID) *CurveFlag

NewCurveFlag creates a CurveFlag with a default curve.

func (*CurveFlag) CertGen added in v1.6.0 

func (f *CurveFlag) CertGen(org string, validUntil time.Time, extraHosts []string) (cert, key []byte, err error)

func (*CurveFlag) ECDSACurve added in v1.6.0 

func (f *CurveFlag) ECDSACurve() (elliptic.Curve, bool)

ECDSACurve returns the elliptic curve described by f, or (nil, false) if the curve is not one of the elliptic curves suitable for ECDSA.

func (*CurveFlag) GenerateKeyPair added in v1.6.0 

func (f *CurveFlag) GenerateKeyPair(rand io.Reader) (pub, priv interface{}, err error)

func (*CurveFlag) MarshalFlag added in v0.7.0 

func (f *CurveFlag) MarshalFlag() (name string, err error)

MarshalFlag satisfies the flags.Marshaler interface.

func (*CurveFlag) UnmarshalFlag added in v0.7.0 

func (f *CurveFlag) UnmarshalFlag(value string) error

UnmarshalFlag satisfies the flags.Unmarshaler interface.

type CurveID added in v0.7.0 

type CurveID int

CurveID specifies a recognized curve through a constant value. 

const (
	CurveP256 CurveID = iota
	CurveP384
	CurveP521
	Ed25519

	// PreferredCurve is the curve that should be used as the application default.
	PreferredCurve = Ed25519
)

Recognized curve IDs.

type ExplicitString added in v1.0.7 

type ExplicitString struct {
	Value string
	// contains filtered or unexported fields
}

ExplicitString is a string value implementing the flags.Marshaler and flags.Unmarshaler interfaces so it may be used as a config struct field. It records whether the value was explicitly set by the flags package. This is useful when behavior must be modified depending on whether a flag was set by the user or left as a default. Without recording this, it would be impossible to determine whether flag with a default value was unmodified or explicitly set to the default.

func NewExplicitString added in v1.0.7 

func NewExplicitString(defaultValue string) *ExplicitString

NewExplicitString creates a string flag with the provided default value.

func (*ExplicitString) ExplicitlySet added in v1.0.7 

func (e *ExplicitString) ExplicitlySet() bool

ExplicitlySet returns whether the flag was explicitly set through the flags.Unmarshaler interface.

func (*ExplicitString) MarshalFlag added in v1.0.7 

func (e *ExplicitString) MarshalFlag() (string, error)

MarshalFlag implements the flags.Marshaler interface.

func (*ExplicitString) String added in v1.0.7 

func (e *ExplicitString) String() string

String implements the fmt.Stringer interface.

func (*ExplicitString) UnmarshalFlag added in v1.0.7 

func (e *ExplicitString) UnmarshalFlag(value string) error

UnmarshalFlag implements the flags.Unmarshaler interface.
