Enum PhysicalType

pub enum PhysicalType {
    Bool = 1,

    String = 20,
    List = 22,
    Array = 23,
    Struct = 24,
}

Physical storage representation of a value. Controls how bytes are laid out in columns and the Value union.

Discriminant values match the C++ PhysicalTypeID for on-disk compatibility.

Implementations

impl PhysicalType

pub const fn fixed_size(&self) -> Option<usize>

Size in bytes of the fixed-size inline representation. Returns None for variable-length types (String, List, Struct).

pub const fn is_fixed_size(&self) -> bool

Whether this type has a fixed size (stored inline in Value).

Trait Implementations

impl Clone for PhysicalType

fn clone(&self) -> PhysicalType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PhysicalType

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

Formats the value using the given formatter.

impl Display for PhysicalType

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

Formats the value using the given formatter.

impl Hash for PhysicalType

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 PartialEq for PhysicalType

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