=head1 Name
SPVM::Document::NativeAPI::StringBuffer - String Buffer Native APIs
=head1 Description
The string buffer native APIs in L<SPVM> are the APIs for string buffers
=head1 Usage
SPVM_API_STRING_BUFFER* string_buffer_api = env->api->string_buffer;
SPVM_API_ALLOCATOR* api_allocator = env->api->allocator;
void* allocator = api_allocator->new_instance();
int32_t capacity = 100;
void* string_buffer = string_buffer_api->new_instance(allocator, capacity);
string_buffer_api->free_instance(string_buffer);
api_allocator->free_instance(allocator);

=head2 new_instance
C<void* (*new_instance)(L<void* allocator|SPVM::Document::NativeAPI::Allocator>, int32_t capacity);>
Creates a new L<string buffer|SPVM::Document::NativeAPI::StringBuffer> given its capacity I<capacity>, and returns it.
=head2 free_instance
C<void (*free_instance)(L<void* string_buffer|SPVM::Document::NativeAPI::StringBuffer>);>
Frees the string buffer I<string_buffer>.
=head2 get_string
C<const char* (*get_string)(L<void* string_buffer|SPVM::Document::NativeAPI::StringBuffer>);>
Returns the string stored in the string buffer I<string_buffer>.
=head2 get_length
C<int32_t (*get_length)(L<void* string_buffer|SPVM::Document::NativeAPI::StringBuffer>);>
Returns the length of the string stored in the string buffer I<string_buffer>.
