}

A ColumnCodec that has been resolved away from Auto.

Invariant: this type can never hold the Auto variant. All on-disk column headers (ColumnMeta.codec) and per-column statistics (ColumnStatistics.codec) use ResolvedColumnCodec, making it a compile-time guarantee that Auto never survives to disk.

The #[repr(u8)] discriminants are identical to the corresponding ColumnCodec discriminants so that on-disk byte values are unchanged. Auto (discriminant 0) is intentionally absent.

Implementations

impl ResolvedColumnCodec

pub fn into_column_codec(self) -> ColumnCodec

Convert back to ColumnCodec for use with codec pipelines that accept the full enum (e.g. encode_i64_pipeline, decode_f64_pipeline).

pub fn as_str(self) -> &'static str

Trait Implementations

impl Clone for ResolvedColumnCodec

fn clone(&self) -> ResolvedColumnCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ResolvedColumnCodec

impl Debug for ResolvedColumnCodec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResolvedColumnCodec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ResolvedColumnCodec

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

Formats the value using the given formatter.

impl Eq for ResolvedColumnCodec

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for ResolvedColumnCodec

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl Hash for ResolvedColumnCodec

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 ResolvedColumnCodec

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for ResolvedColumnCodec

impl ToMessagePack for ResolvedColumnCodec

fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the MessagePack representation of this value into the provided writer.
