Protobuf supported field types

TODO: Groups (even if deprecated)

Variants

Int32

Protobuf int32

Remarks

Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.

Int64

Protobuf int64

Remarks

Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.

Uint32

Protobuf uint32

Remarks

Uses variable-length encoding.

Uint64

Protobuf uint64

Remarks

Uses variable-length encoding.

Sint32

Protobuf sint32

Remarks

Uses ZigZag variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.

Sint64

Protobuf sint64

Remarks

Uses ZigZag variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.

Bool

Protobuf bool

Fixed64

Protobuf fixed64

Remarks

Always eight bytes. More efficient than uint64 if values are often greater than 2^56.

Sfixed64

Protobuf sfixed64

Remarks

Always eight bytes.

Double

Protobuf double

String

Protobuf string

Remarks

A string must always contain UTF-8 encoded or 7-bit ASCII text.

Bytes

Protobuf bytes

Remarks

May contain any arbitrary sequence of bytes.

Fixed32

Protobut fixed32

Remarks

Always four bytes. More efficient than uint32 if values are often greater than 2^28.

Sfixed32

Protobut sfixed32

Remarks

Always four bytes.

Float

Protobut float

MessageOrEnum(String)

Protobuf message or enum (holds the name)

Map(Box<(FieldType, FieldType)>)

Protobut map

Group(Vec<Field>)

Protobuf group (deprecated)

Trait Implementations

impl Clone for FieldType

fn clone(&self) -> FieldType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for FieldType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FieldType

fn eq(&self, other: &FieldType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for FieldType
