Implementations

impl Described

pub fn sql_repr(&self) -> String

Represent the data type in sql.

For example: “INT”, “VARCHAR(100)”.

pub fn new( field: impl Into<String>, ty: Ty, length: impl Into<Option<usize>>, ) -> Self

Create a new column description without primary-key/compression feature.

pub fn is_primary_key(&self) -> bool

Return true if the field is primary key.

pub fn is_tag(&self) -> bool

Return true if the field is tag.

Trait Implementations

impl Clone for Described

fn clone(&self) -> Described

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Described

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Described

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Described

fn eq(&self, other: &Described) -> 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 Serialize for Described

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Described
