Package: effect
Module: SchemaIssue

SchemaIssue.Composite

Represents a schema issue that groups multiple child issues under a single schema node.

When to use

Use when you need to walk the issue tree for struct/tuple schemas that collect all field errors rather than failing on the first.

Details

• issues is a non-empty readonly array (at least one child).
• actual is Option.some(value) when the input was present, or Option.none() when absent.
• Formatters flatten Composite by recursing into each child.

See

• AnyOf — used for union no-match errors (similar but different semantics)
• Pointer — adds path context to individual issues

Signature

declare class Composite { constructor(
    /**
     * The schema that caused the issue.
     */
    ast: SchemaAST.AST,
    /**
     * The input value that caused the issue.
     */
    actual: Option.Option<unknown>,
    /**
     * The issues that occurred.
     */
    issues: readonly [Issue, ...Array<Issue>]
  ) }
