Enum FieldValue 

#[non_exhaustive]
pub enum FieldValue {
    I64(i64),
    F64(f64),
    Bool(bool),
    String(String),
    Bytes(Vec<u8>),
    PooledString(InternedString),
    StackFrames(StackFrames),
    PooledStackFrames(InternedStackFrames),
    Varint(u64),
    StringMap(Vec<(Vec<u8>, Vec<u8>)>),
    List(Vec<FieldValue>),
    Map(Vec<(FieldValue, FieldValue)>),
    None,
}

Available on crate feature dial9 only.

Owned field value. Decoded from the wire format.

Note: U8, U16, and U32 wire types are decoded into Varint(v as u64). The original fixed-width type is not preserved — use the schema’s FieldType if you need to distinguish them.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

I64(i64)

F64(f64)

Bool(bool)

String(String)

Bytes(Vec<u8>)

PooledString(InternedString)

StackFrames(StackFrames)

PooledStackFrames(InternedStackFrames)

Varint(u64)

StringMap(Vec<(Vec<u8>, Vec<u8>)>)

List(Vec<FieldValue>)

Self-describing list: each element carries its own type tag.

Map(Vec<(FieldValue, FieldValue)>)

Self-describing map: each entry carries type tags for key and value.

None

Absent optional field.

Implementations

impl FieldValue

pub fn string(s: &str) -> FieldValue

pub fn field_type_tag(&self) -> u8

Returns the FieldType wire tag corresponding to this value’s type. Used for self-describing encoding in DynamicList/DynamicMap.

impl FieldValue

pub fn encode(&self, w: &mut impl Write) -> Result<(), Error>

Encode this value into the writer.

pub fn decode(field_type: FieldType, data: &[u8]) -> Option<(FieldValue, &[u8])>

Decode a value of the given type from the buffer. Returns (value, remaining_slice).

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<(), Error>

Formats the value using the given formatter.

impl PartialEq for FieldValue

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for FieldValue

Available on crate feature serde only.

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
