Detailed Description

Growable character buffer that stays NUL terminated after every append.

Constructor & Destructor Documentation

StringBuffer()

rex::string::StringBuffer::StringBuffer ( size_t initial_capacity = 0 )

explicit

Allocates the buffer.

Parameters

initial_capacity

Initial capacity in bytes. The buffer holds at least 16 KiB.

Member Function Documentation

Append()

void rex::string::StringBuffer::Append	(	char	c,
		size_t	count )

Appends a character count times.

AppendFormat()

template<typename... Args>

void rex::string::StringBuffer::AppendFormat ( std::format_string< const Args &... > format, const Args &... args )

inline

Appends text formatted with std::format.

Parameters

format

Format string, checked at compile time.

AppendVarargs()

void rex::string::StringBuffer::AppendVarargs	(	const char *	format,
		va_list	args )

Appends text formatted with vsnprintf.

Parameters

format

printf format string.

GetBuffer()

char * rex::string::StringBuffer::GetBuffer ( ) const

inline

Returns the characters. The contents are NUL terminated.

GetLength()

size_t rex::string::StringBuffer::GetLength ( ) const

inline

Returns the content length. The count excludes the terminator.

Reset()

void rex::string::StringBuffer::Reset

(

)

Empties the buffer and keeps its capacity.

ToBytes()

std::vector< u8 > rex::string::StringBuffer::ToBytes

(

)

const

Copies the contents into a byte vector.

Returns

The contents without the terminator.

ToStringView()

std::string_view rex::string::StringBuffer::ToStringView

(

)

const

Returns a view of the contents. The view is valid until the next append or destruction.
