Type	Name
size_t	envisage_result_length () noexcept const Returns the buffer size in bytes needed for hexadecimal dump of a passed slice.
bool	is_empty () noexcept const Checks whether a passed slice is empty, and therefore there will be no output bytes.
bool	is_erroneous () noexcept const Checks whether the content of the passed slice could be encoded; this encoder always returns false .
::std::ostream &	output (::std::ostream & out) const Output hexadecimal dump of passed slice to the std::ostream.
constexpr	to_hex (const slice & source, bool uppercase=false, unsigned wrap_width=0) noexcept
char *	write_bytes (char * dest, size_t dest_size) const Fills the buffer by hexadecimal dump of a passed slice.

Public Functions Documentation

function envisage_result_length

Returns the buffer size in bytes needed for hexadecimal dump of a passed slice.

inline size_t mdbx::to_hex::envisage_result_length () noexcept const

---

function is_empty

Checks whether a passed slice is empty, and therefore there will be no output bytes.

inline bool mdbx::to_hex::is_empty () noexcept const

---

function is_erroneous

Checks whether the content of the passed slice could be encoded; this encoder always returns false .

inline bool mdbx::to_hex::is_erroneous () noexcept const

---

function output

Output hexadecimal dump of passed slice to the std::ostream.

::std::ostream & mdbx::to_hex::output (
    ::std::ostream & out
) const

Exception:

• std::ios_base::failure corresponding to std::ostream::write() behaviour.

function to_hex

inline constexpr mdbx::to_hex::to_hex (
    const slice & source,
    bool uppercase=false,
    unsigned wrap_width=0
) noexcept

---

function write_bytes

Fills the buffer by hexadecimal dump of a passed slice.

char * mdbx::to_hex::write_bytes (
    char * dest,
    size_t dest_size
) const

Exception:

• std::length_error if given buffer is too small.
