Kinds of semantic errors.

Variants

UnresolvedColumn

Column reference could not be resolved.

Fields

table: Option<String>

column: String

AmbiguousColumn

Column reference is ambiguous (exists in multiple tables).

Fields

column: String

candidates: Vec<String>

UnresolvedTable

Table or alias not found.

Fields

name: String

DuplicateAlias

Duplicate alias in the same scope.

Fields

alias: String

FunctionArityMismatch

Function called with wrong number of arguments.

Fields

function: String

expected: FunctionArity

actual: usize

NoTablesSpecifiedForStar

SELECT * used without any tables in scope.

ImplicitTypeCoercion

Type coercion warning (not fatal).

Fields

from: TypeAffinity

to: TypeAffinity

context: String

Trait Implementations

impl Clone for SemanticErrorKind

fn clone(&self) -> SemanticErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticErrorKind

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

Formats the value using the given formatter.

impl PartialEq for SemanticErrorKind

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