Detailed Description

Describes a field in a Protocol Buffer message, similar to google::protobuf::FieldDescriptor.

This structure holds metadata about a field, including its type, number, repetition status, default value, and any associated options. It supports scalar types, strings, enums, and more.

Member Data Documentation

b

bool pbl_field_descriptor_t::b

Default value for bool fields.

basic_info

pbl_node_t pbl_field_descriptor_t::basic_info

Basic metadata node (e.g., name, documentation).

d

double pbl_field_descriptor_t::d

Default value for double fields.

[union]

union { ... } pbl_field_descriptor_t::default_value

Union holding the parsed default value for the field.

The actual member used depends on the field type.

e

const pbl_enum_value_descriptor_t* pbl_field_descriptor_t::e

Default enum value descriptor.

f

float pbl_field_descriptor_t::f

Default value for float fields.

has_default_value

bool pbl_field_descriptor_t::has_default_value

True if a default value is explicitly declared.

i32

int32_t pbl_field_descriptor_t::i32

Default value for int32 fields.

i64

int64_t pbl_field_descriptor_t::i64

Default value for int64 fields.

is_repeated

bool pbl_field_descriptor_t::is_repeated

True if the field is repeated.

is_required

bool pbl_field_descriptor_t::is_required

True if the field is required.

number

int pbl_field_descriptor_t::number

Field number as defined in the .proto schema.

options_node

pbl_node_t* pbl_field_descriptor_t::options_node

Pointer to options metadata node, if present.

orig_default_value

char* pbl_field_descriptor_t::orig_default_value

Original default value string from the schema.

s

char* pbl_field_descriptor_t::s

Default value for string or bytes fields.

string_or_bytes_default_value_length

int pbl_field_descriptor_t::string_or_bytes_default_value_length

Length of string or bytes default value, if applicable.

type

int pbl_field_descriptor_t::type

Field type identifier (see PROTOBUF_TYPE_XXX in protobuf-helper.h).

type_name

char* pbl_field_descriptor_t::type_name

Optional type name for message or enum fields.

u32

uint32_t pbl_field_descriptor_t::u32

Default value for uint32 fields.

u64

uint64_t pbl_field_descriptor_t::u64

Default value for uint64 fields.
