Enum SourceKind 

pub enum SourceKind {
    Root,
    Table,

    Cte,
    Virtual,
    Unknown,
}

Semantic kind of a source registered in a scope.

Variants

Root

Unknown

Unresolved or synthetic fallback source

Trait Implementations

impl Clone for SourceKind

fn clone(&self) -> SourceKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SourceKind

impl Debug for SourceKind

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

Formats the value using the given formatter.

impl Default for SourceKind

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SourceKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SourceKind

impl PartialEq for SourceKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
