parser::parser (6 of 8 overloads)

Constructor.

Synopsis
template<
    std::size_t N>
parser(
    storage_ptr sp,
    parse_options const& opt,
    unsigned char(&) buffer[N]);
Description

This constructs a new parser which first uses the caller-owned storage buffer for temporary storage, falling back to the memory resource sp if needed. The parser will use the specified parsing options.

The parsed value will use the default memory resource for storage. To use a different resource, call reset after construction.

Complexity

Constant.

Exception Safety

No-throw guarantee.

Parameters

Name

Description

sp

The memory resource to use for temporary storage after buffer is exhausted.

opt

The parsing options to use.

buffer

A buffer for the parser to use for temporary storage. Ownership is not transferred, the caller is responsible for ensuring the lifetime of buffer extends until the parser is destroyed.
