Enum ErrorCode

pub enum ErrorCode {
    SyntaxError,

A machine-readable classification for a ScytheError.

Marked #[non_exhaustive] so that adding a variant is not a breaking change for downstream crates matching on it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SyntaxError

UnknownTable

UnknownColumn

UnknownFunction

AmbiguousColumn

TypeMismatch

MissingAnnotation

InvalidAnnotation

ColumnCountMismatch

DuplicateAlias

InvalidRecursion

InvalidConfig

The user’s configuration is wrong — an unknown [[sql.gen]] key, an unrecognized option value, a malformed manifest override. Distinct from ErrorCode::InternalError, which means scythe itself is at fault.

UnresolvedType

A construct the analyzer diagnosed correctly but that has no neutral-type representation scythe can hand to codegen: a set-returning function’s anonymous record column referenced in select-list position (json_each, json_populate_record, …), a multi-element ROW(...)/ tuple constructor, or any other expression infer_expr_type genuinely cannot resolve. Distinct from ErrorCode::TypeMismatch, which covers an expression that could have been typed but nothing in the query gave it one (a bare NULL/placeholder, both arms of a UNION untyped) — this code is for input scythe understood and rejected on purpose (#223), mirroring the existing one-code-per-marker-family pattern (ErrorCode::AmbiguousColumn, ErrorCode::UnknownColumn, ErrorCode::UnknownFunction) rather than folding into TypeMismatch.

InternalError
