Enum Type 

pub enum Type {
    Unsigned,
    Signed,
    Float,
    Boolean,
    Date,
    DateTime,
    NULL,
    Text,
}

Data type detected for a CSV field.

Variants

Unsigned

Unsigned integer (non-negative whole number).

Signed

Signed integer (whole number, possibly negative).

Float

Floating point number.

Boolean

Boolean value (true/false, yes/no, 0/1, etc.).

Date

Date value (without time component).

DateTime

DateTime value (date with time component).

NULL

Null/empty value.

Text

Text/string value (fallback type).

Implementations

impl Type

pub const COUNT: usize = 8

Number of variants in the Type enum.

pub const fn as_index(&self) -> usize

Returns the index for this type (0-7), suitable for array indexing. This index is based on type priority (see priority()), not enum declaration order: NULL=0, Boolean=1, Unsigned=2, Signed=3, Float=4, Date=5, DateTime=6, Text=7.

pub fn is_numeric(&self) -> bool

Returns true if this type is numeric.

pub fn is_temporal(&self) -> bool

Returns true if this type is temporal.

pub const fn priority(&self) -> u8

Returns the type priority for type inference. Higher priority types are preferred when merging types.

pub fn merge(self, other: Type) -> Type

Merge two types, returning the most general type that can represent both.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate 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 Default for Type

fn default() -> Type

Returns the “default value” for a type.

impl Display for Type

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

Formats the value using the given formatter.

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 Copy for Type

impl Eq for Type

impl StructuralPartialEq for Type
