Detailed Description

Non-serialized, template data structure for a key/value pair. For strings and byte arrays, it only has a pointer to the actual data. For integers, it provides storage for integers up to 32-bits wide. The Tuplet data structure is useful when creating dictionaries from values that are already stored in arbitrary buffers. See also Tuple, with is the header of a serialized key/value pair.

Member Data Documentation

@1

union { ... }

See documentation of .bytes, .cstring and .integer fields.

Anonymous union containing the reference to the Tuplet's value, being either a byte array, c-string or integer. See documentation of .bytes, .cstring and .integer fields.

@16

union { ... }

See documentation of .bytes, .cstring and .integer fields.

Anonymous union containing the reference to the Tuplet's value, being either a byte array, c-string or integer. See documentation of .bytes, .cstring and .integer fields.

length

const uint16_t Tuplet::length

Length of the data.

Length of the c-string, including terminating zero.

storage

uint32_t Tuplet::storage

Actual storage of the integer. The signedness can be derived from the .type value.

type

TupleType Tuplet::type

The type of the Tuplet. This determines which of the struct fields in the anonymomous union are valid.
