Struct PolymorphicValue 

pub struct PolymorphicValue { /* private fields */ }

Polymorphic value that encodes small values inline

This is the core type for space-efficient value storage. Small values (≤7 bytes) are stored directly without allocation.

Thread Safety

PolymorphicValue is not thread-safe by default. Use AtomicValue for concurrent access.

Implementations

impl PolymorphicValue

pub fn null() -> Self

Create a null value

pub fn bool(v: bool) -> Self

Create a boolean value

pub fn int(v: i64) -> Self

Create an integer value

Values in range [-2^55, 2^55-1] are stored inline.

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

Create a string value

Strings ≤7 bytes are stored inline.

pub fn bytes(b: &[u8]) -> Self

Create a bytes value

Bytes ≤7 are stored inline.

pub fn float(v: f64) -> Self

Create a float value

pub fn tag(&self) -> ValueTag

Get value tag

pub fn is_null(&self) -> bool

Check if value is null

pub fn is_inline(&self) -> bool

Check if value is stored inline

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

Get as boolean

pub fn as_int(&self) -> Option<i64>

Get as integer

pub fn as_float(&self) -> Option<f64>

Get as float

pub fn as_str(&self) -> Option<String>

Get as string (copies inline data if needed)

For inline strings, returns a new String. For heap strings, returns from heap.

pub fn as_heap_str(&self) -> Option<&str>

Get heap string as reference (only works for heap strings)

pub fn as_bytes(&self) -> Option<&[u8]>

Get as bytes reference (only works for heap bytes)

pub fn inline_bytes_copy(&self) -> Option<Vec<u8>>

Get raw inline bytes (copies out of packed representation)

pub fn encoded_size(&self) -> usize

Get encoded size in bytes

pub fn to_bytes(&self) -> Vec<u8>

Serialize to bytes

pub fn from_bytes(data: &[u8]) -> Option<Self>

Deserialize from bytes

Trait Implementations

impl Clone for PolymorphicValue

fn clone(&self) -> PolymorphicValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolymorphicValue

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

Formats the value using the given formatter.

impl Default for PolymorphicValue

fn default() -> Self

Returns the “default value” for a type.
