Enum FieldValue 

pub enum FieldValue {
    Varint(Varint),
    I32([u8; 4]),
    I64([u8; 8]),
    Len(Vec<u8>),
}

A raw field value read from the wire

This represents the raw bytes of a field value without semantic interpretation. The caller is responsible for converting these raw values to the appropriate types based on the field’s schema definition.

Variants

Varint(Varint)

Variable-width integers (Int32, Int64, UInt32, UInt64, SInt32, SInt64, Bool, Enum)

I32([u8; 4])

32-bit fixed-width values (Fixed32, SFixed32, Float)

I64([u8; 8])

64-bit fixed-width values (Fixed64, SFixed64, Double)

Len(Vec<u8>)

Length-delimited values (String, Bytes, embedded messages, packed repeated fields)

Implementations

impl FieldValue

pub fn from_varint(varint: Varint) -> Self

Create a field value from a Varint

pub fn from_uint64(value: u64) -> Self

Create a field value from a UInt64 protobuf type

pub fn from_uint32(value: u32) -> Self

Create a field value from a UInt32 protobuf type

pub fn from_sint64(value: i64) -> Self

Create a field value from a SInt64 protobuf type (ZigZag encoded)

pub fn from_sint32(value: i32) -> Self

Create a field value from a SInt32 protobuf type (ZigZag encoded)

pub fn from_int64(value: i64) -> Self

Create a field value from an Int64 protobuf type (non-ZigZag)

pub fn from_int32(value: i32) -> Self

Create a field value from an Int32 protobuf type (non-ZigZag)

pub fn from_bool(value: bool) -> Self

Create a field value from a Bool protobuf type

pub fn from_fixed32(value: u32) -> Self

Create a field value from a Fixed32 protobuf type

pub fn from_sfixed32(value: i32) -> Self

Create a field value from a SFixed32 protobuf type

pub fn from_float(value: f32) -> Self

Create a field value from a Float protobuf type

pub fn from_fixed64(value: u64) -> Self

Create a field value from a Fixed64 protobuf type

pub fn from_sfixed64(value: i64) -> Self

Create a field value from a SFixed64 protobuf type

pub fn from_double(value: f64) -> Self

Create a field value from a Double protobuf type

pub fn from_bytes(data: Vec<u8>) -> Self

Create a field value from raw bytes (Bytes protobuf type)

pub fn from_string(s: String) -> Self

Create a field value from a String protobuf type

pub fn encoded_size(&self) -> usize

Calculate the encoded size of this field value in bytes (excluding the tag)

For Len values, this includes the length varint plus the data bytes.

Trait Implementations

impl Clone for FieldValue

fn clone(&self) -> FieldValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldValue

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

Formats the value using the given formatter.

impl PartialEq for FieldValue

fn eq(&self, other: &FieldValue) -> 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.
