Detailed Description

String with extra allocation for ease of use with parser::parse()

This is a move-only class, it cannot be copied.

Definition at line 23 of file padded_string.h.

Constructor & Destructor Documentation

padded_string() [1/5]

simdjson::padded_string::padded_string ( size_t  length )

inlineexplicitnoexcept

Create a new padded string buffer.

Parameters

length

the size of the string.

Definition at line 48 of file padded_string-inl.h.

padded_string() [2/5]

simdjson::padded_string::padded_string ( const char *  data, size_t  length  )

inlineexplicitnoexcept

Create a new padded string by copying the given input.

Parameters

data	the buffer to copy
length	the number of bytes to copy

Definition at line 51 of file padded_string-inl.h.

padded_string() [3/5]

simdjson::padded_string::padded_string ( const std::string &  str_ )

inlinenoexcept

Create a new padded string by copying the given input.

Parameters

str_	the string to copy

Definition at line 72 of file padded_string-inl.h.

padded_string() [4/5]

simdjson::padded_string::padded_string ( std::string_view  sv_ )

inlinenoexcept

Create a new padded string by copying the given input.

Parameters

sv_	the string to copy

Definition at line 81 of file padded_string-inl.h.

padded_string() [5/5]

simdjson::padded_string::padded_string ( padded_string &&  o )

inlinenoexcept

Move one padded string into another.

The original padded string will be reduced to zero capacity.

Parameters

o	the string to move.

Definition at line 92 of file padded_string-inl.h.

~padded_string()

simdjson::padded_string::~padded_string ( )

inlinenoexcept

Definition at line 116 of file padded_string-inl.h.

Member Function Documentation

data() [1/2]

const char * simdjson::padded_string::data ( ) const

inlinenoexcept

The string data.

Definition at line 124 of file padded_string-inl.h.

data() [2/2]

char * simdjson::padded_string::data ( )

inlinenoexcept

The string data.

Definition at line 126 of file padded_string-inl.h.

length()

size_t simdjson::padded_string::length ( ) const

inlinenoexcept

The length of the string.

Does not include padding.

Definition at line 122 of file padded_string-inl.h.

load()

simdjson_result< padded_string > simdjson::padded_string::load ( std::string_view  path )

inlinestaticnoexcept

Load this padded string from a file.

Windows and Unicode

Windows users who need to read files with non-ANSI characters in the name should set their code page to UTF-8 (65001) before calling this function. This should be the default with Windows 11 and better. Further, they may use the AreFileApisANSI function to determine whether the filename is interpreted using the ANSI or the system default OEM codepage, and they may call SetFileApisToOEM accordingly.

Returns

IO_ERROR on error. Be mindful that on some 32-bit systems, the file size might be limited to 2 GB.

Parameters

path	the path to the file.

Definition at line 134 of file padded_string-inl.h.

operator padded_string_view()

simdjson::padded_string::operator padded_string_view ( ) const

inlinenoexcept

Create a padded_string_view with the same content.

Definition at line 130 of file padded_string-inl.h.

operator std::string_view()

simdjson::padded_string::operator std::string_view ( ) const

inline

Create a std::string_view with the same content.

Definition at line 128 of file padded_string-inl.h.

operator=()

padded_string & simdjson::padded_string::operator= ( padded_string &&  o )

inlinenoexcept

Move one padded string into another.

The original padded string will be reduced to zero capacity.

Parameters

o	the string to move.

Definition at line 98 of file padded_string-inl.h.

size()

size_t simdjson::padded_string::size ( ) const

inlinenoexcept

The length of the string.

Does not include padding.

Definition at line 120 of file padded_string-inl.h.

swap()

void simdjson::padded_string::swap ( padded_string &  o )

inlinenoexcept

Definition at line 107 of file padded_string-inl.h.

u8data()

const uint8_t * simdjson::padded_string::u8data ( ) const

inlinenoexcept

Definition at line 94 of file padded_string.h.
