Struct WireVarInt 

pub struct WireVarInt(/* private fields */);

Variable sized integer Protobuf wire value used to encode the Protobuf types int32, int64, uint32, uint64, sint32, sint64, bool and enum.

Implementations

impl WireVarInt

pub fn from_raw(raw_value: u64) -> WireVarInt

pub fn from_bool(value: bool) -> WireVarInt

Encode the given bool as Protobuf bool.

pub fn from_uint32(value: u32) -> WireVarInt

Encode the given u32 as Protobuf uint32.

pub fn from_int32(value: i32) -> WireVarInt

Encode the given i32 as Protobuf int32 (encodes using two’s complements).

pub fn from_sint32(value: i32) -> WireVarInt

Encode the given i32 as Protobuf sint32 (encodes using ZigZag).

pub fn from_uint64(value: u64) -> WireVarInt

Encode the given u64 as Protobuf uint64.

pub fn from_int64(value: i64) -> WireVarInt

Encode the given i32 as Protobuf int64 (encodes using two’s complements).

pub fn from_sint64(value: i64) -> WireVarInt

Encode the given i64 as Protobuf sint64 (encodes using ZigZag).

pub fn raw(&self) -> u64

Returns the underlying stored encoded value (same as Self::as_uint64).

pub fn try_as_bool(&self) -> Option<bool>

Try to interpret the varint as a Protobuf bool.

If the varint contains any value other then 1 or 0 None is returned.

pub fn try_as_uint32(&self) -> Option<u32>

Try to interpret the varint as a Protobuf uint32.

If the varint contains a value that is bigger then 32 bits None is returned instead.

pub fn try_as_int32(&self) -> Option<i32>

Try to interpret the varint as a Protobuf int32 (encoded using two’s complements).

If the varint contains a value that is bigger then 32 bits None is returned instead.

pub fn try_as_sint32(&self) -> Option<i32>

Try to interpret the varint as a Protobuf sint32 (encoded using ZigZag).

If the varint contains a value that is bigger then 32 bits None is returned instead.

pub fn as_uint64(&self) -> u64

Interpret the varint as a Protobuf uint64.

pub fn as_int64(&self) -> i64

Interpret the varint as a Protobuf int64 (encoded using two’s complements).

pub fn as_sint64(&self) -> i64

Interpret the varint as a Protobuf sint64 (encoded using ZigZag).

pub fn tag_byte_len(field_number: FieldNumber) -> i32

Returns the byte len of a encoded “tag” with the passed field number.

Tag is the value written before a message field value is written.

pub fn int32_byte_len(value: i32) -> i32

Returns the encoded byte len of a “int32” encoded as varint (encoded using two’s complements).

pub fn int64_byte_len(value: i64) -> i32

Returns the encoded byte len of a “int64” encoded as varint (encoded using two’s complements).

pub fn uint32_byte_len(value: u32) -> i32

Returns the encoded byte len of a “uint32” encoded as varint.

pub fn uint64_byte_len(value: u64) -> i32

Returns the encoded byte len of a “uint64” encoded as varint.

pub fn sint32_byte_len(value: i32) -> i32

Returns the encoded byte len of a “sint32” encoded as varint (encoded using zig zag).

pub fn sint64_byte_len(value: i64) -> i32

Returns the encoded byte len of a “sint64” encoded as varint (encoded using zig zag).

Trait Implementations

impl Clone for WireVarInt

fn clone(&self) -> WireVarInt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WireVarInt

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

Formats the value using the given formatter.

impl Hash for WireVarInt

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 Ord for WireVarInt

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for WireVarInt

fn eq(&self, other: &WireVarInt) -> 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 PartialOrd for WireVarInt

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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