Constructor & Destructor Documentation

Hash()

nix::Hash::Hash

(

HashType

type

)

Create a zero-filled hash object.

Member Function Documentation

base16Len()

size_t nix::Hash::base16Len ( ) const

inline

Returns the length of a base-16 representation of this hash.

base32Len()

size_t nix::Hash::base32Len ( ) const

inline

Returns the length of a base-32 representation of this hash.

base64Len()

size_t nix::Hash::base64Len ( ) const

inline

Returns the length of a base-64 representation of this hash.

operator!=()

bool nix::Hash::operator!=

(

const Hash &

h2

)

const

Check whether two hash are not equal.

operator<()

bool nix::Hash::operator<

(

const Hash &

h

)

const

For sorting.

operator==()

bool nix::Hash::operator==

(

const Hash &

h2

)

const

Check whether two hash are equal.

parseAny()

Hash nix::Hash::parseAny ( std::string_view s, std::optional< HashType > type )

static

Parse the hash from a string representation in the format "[<type>:]<base16|base32|base64>" or "<type>-<base64>" (a Subresource Integrity hash expression). If the 'type' argument is not present, then the hash type must be specified in the string.

parseAnyPrefixed()

Hash nix::Hash::parseAnyPrefixed ( std::string_view s )

static

Parse a hash from a string representation like the above, except the type prefix is mandatory is there is no separate arguement.

parseNonSRIUnprefixed()

Hash nix::Hash::parseNonSRIUnprefixed ( std::string_view s, HashType type )

static

Parse a plain hash that musst not have any prefix indicating the type. The type is passed in to disambiguate.

to_string()

std::string nix::Hash::to_string	(	Base	base,
		bool	includeType ) const

Return a string representation of the hash, in base-16, base-32 or base-64. By default, this is prefixed by the hash type (e.g. "sha256:").
