Enum parquet::basic::Type

pub enum Type {
    BOOLEAN,
    INT32,
    INT64,
    INT96,
    FLOAT,
    DOUBLE,
    BYTE_ARRAY,
    FIXED_LEN_BYTE_ARRAY,
}

Types supported by Parquet.

These physical types are intended to be used in combination with the encodings to control the on disk storage format. For example INT16 is not included as a type since a good encoding of INT32 would handle this.

Variants

BOOLEAN

A boolean value.

INT32

32-bit signed integer.

INT64

64-bit signed integer.

INT96

96-bit signed integer for timestamps.

FLOAT

IEEE 754 single-precision floating point value.

DOUBLE

IEEE 754 double-precision floating point value.

BYTE_ARRAY

Arbitrary length byte array.

FIXED_LEN_BYTE_ARRAY

Fixed length byte array.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Display for Type

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

Formats the value using the given formatter.

impl From<Type> for Type

fn from(value: Type) -> Self

Converts to this type from the input type.

impl FromStr for Type

type Err = ParquetError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for Type

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 Type

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

impl TryFrom<Type> for Type

type Error = ParquetError

The type returned in the event of a conversion error.

fn try_from(value: Type) -> Result<Self>

Performs the conversion.

impl Copy for Type

impl Eq for Type

impl StructuralPartialEq for Type
