Enumeration Type Documentation

◆ Grow_status

Error statuses for classes that use Grow_calculator.

Enumerator
success 

A grow operation succeeded.

The data structure is now of the new size.

exceeds_max_size 

A grow operation could not be performed because there is a configured maximum size.

The data structure is unchanged.

out_of_memory 

A grow operation failed because memory allocation failed.

The data structure is unchanged.

Function Documentation

◆ debug_string()

std::string mysql::binlog::event::compression::buffer::debug_string ( Grow_status  status)

Return a string that describes each enumeration value.

◆ operator<<()

std::ostream & mysql::binlog::event::compression::buffer::operator<< ( std::ostream &  stream,
Grow_status  status 
)

Write a string that describes the enumeration value to the stream.

Variable Documentation

◆ default_preallocated_managed_buffer_size

constexpr std::size_t mysql::binlog::event::compression::buffer::default_preallocated_managed_buffer_size
constexpr
Initial value:
=
std::size_t(8 * 1024)

◆ invalid_grow_status_string

const std::string mysql::binlog::event::compression::buffer::invalid_grow_status_string = "invalid"

Return value from debug_string(Grow_status) when the parameter is not a valid value.
