pub enum ColumnMappingMode {
    None,
    Id,
    Name,
}

Modes of column mapping a table can be in

Variants

None

Name

Columns are mapped to a physical name

Trait Implementations

impl Clone for ColumnMappingMode

fn clone(&self) -> ColumnMappingMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnMappingMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ColumnMappingMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for ColumnMappingMode

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<ColumnMappingMode, <Self as FromStr>::Err>

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

impl PartialEq for ColumnMappingMode

fn eq(&self, other: &ColumnMappingMode) -> 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 ColumnMappingMode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for ColumnMappingMode

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from( s: &str, ) -> Result<ColumnMappingMode, <Self as TryFrom<&str>>::Error>

Performs the conversion.
