Apply percent-encoding to a string

Synopsis

template<class CharSet>
std::size_t
encode(
    char* dest,
    std::size_t size,
    core::string_view s,
    CharSet const& unreserved,
    encoding_opts opt = = {});

template<
    class StringToken = string_token::return_string,
    class CharSet>
StringToken::result_type
encode(
    core::string_view s,
    CharSet const& unreserved,
    encoding_opts opt = = {},
    StringToken&& token) noexcept;

Description

This function applies percent-encoding to the string using the given options and character set. The destination buffer provided by the caller is used to store the result, which may be truncated if there is insufficient space.

char buf[100];
assert( encode( buf, sizeof(buf), "Program Files", pchars ) == 15 );

Throws nothing.

2.1. Percent-Encoding (rfc3986)

Return Value

The number of characters written to the destination buffer.

Parameters

unreserved	The set of characters that is not percent-encoded.
opt	The options for encoding. If this parameter is omitted, the default options are used.
token	A string token.
