pct_string_view::decode

Return the string with percent-decoding.

Synopsis

template<
    class StringToken = string_token::return_string>
StringToken::result_type
decode(
    decode_opts opt = {},
    StringToken&& token = {}) const;

This function converts percent escapes in the string into ordinary characters and returns the result. When called with no arguments, the return type is std::string. Otherwise, the return type and style of output is determined by which string token is passed.

Example

assert( pct_string_view( "Program%20Files" ).decode() == "Program Files" );

Complexity

Linear in this->size().

Exception Safety

Calls to allocate may throw. String tokens may throw exceptions.

Parameters

Name	Description
`opt`	The options for encoding. If this parameter is omitted, the default options will be used.
`token`	An optional string token. If this parameter is omitted, then a new `std::string` is returned. Otherwise, the function return type will be the result type of the token.
