Variants

Double

0 is reserved for errors. Order is weird for historical reasons.

FloatInt64

Not ZigZag encoded. Negative numbers take 10 bytes. Use TYPE_SINT64 if negative values are likely.

Uint64Int32

Not ZigZag encoded. Negative numbers take 10 bytes. Use TYPE_SINT32 if negative values are likely.

Fixed64Fixed32BoolStringGroup

Tag-delimited aggregate. Group type is deprecated and not supported in proto3. However, Proto3 implementations should still be able to parse the group wire format and treat group fields as unknown fields.

Message

Length-delimited aggregate.

Bytes

New in version 2.

Uint32EnumSfixed32Sfixed64Sint32

Uses ZigZag encoding.

Sint64

Uses ZigZag encoding.

Methods

impl Type

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Type.

pub fn from_i32(value: i32) -> Option<Type>

Converts an i32 to a Type, or None if value is not a valid variant.

Trait Implementations

impl Ord for Type

fn cmp(&self, other: &Type) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl From<Type> for i32

fn from(value: Type) -> i32

Performs the conversion.

impl Eq for Type

impl PartialOrd<Type> for Type

fn partial_cmp(&self, other: &Type) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Default for Type

fn default() -> Type

Returns the "default value" for a type.

impl Copy for Type

impl PartialEq<Type> for Type

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

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

This method tests for !=.

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Hash for Type

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, 

Feeds a slice of this type into the given [Hasher].
