Package: effect
Module: SchemaIssue

SchemaIssue.OneOf

Represents a schema issue produced when a value matches multiple members of a union that is configured to allow exactly one match (oneOf mode).

When to use

Use when you need to detect ambiguous union matches when oneOf validation is enabled.

Details

• ast is the Union AST node.
• actual is the raw input value (plain unknown).
• successes lists the AST nodes of each member that accepted the input.
• The default formatter renders this as "Expected exactly one member to match the input <actual>".

See

• AnyOf — the opposite: no members matched

Signature

declare class OneOf { constructor(
    /**
     * The schema that caused the issue.

    ast: SchemaAST.Union,
    /**
     * The input value that caused the issue.
     */
    actual: unknown,
    /**
     * The schemas that were successful.
     */
    successes: ReadonlyArray<SchemaAST.AST>
  ) }
