Filter) => {
return const makeFilter: <T>(
filter: (
input: T,
ast: SchemaAST.AST,
options: SchemaAST.ParseOptions
) => FilterOutput,
annotations?: Annotations.Filter | undefined,
abort?: boolean
) => SchemaAST.Filter<T>
Creates a custom validation filter from a predicate function.
Details
The predicate receives the decoded input value, the schema AST, and parse
options, and returns a FilterOutput. Non-success outputs are normalized into
schema issues. The annotations parameter annotates the filter itself; with
the default formatter, failures use message first, expected second, and
<filter> when neither is provided.
When abort is true, parsing stops after this filter fails instead of
collecting later check failures.
Example (Reporting failure at a nested path)
import { Schema } from "effect"
const schema = Schema.Struct({ password: Schema.String, confirmPassword: Schema.String }).check(
Schema.makeFilter((o) =>
o.password === o.confirmPassword
? undefined
: { path: ["password"], issue: "password and confirmPassword must match" }
)
)
console.log(String(Schema.decodeUnknownExit(schema)({ password: "123456", confirmPassword: "1234567" })))
// Failure(Cause([Fail(SchemaError: password and confirmPassword must match
// at ["password"])]))
Example (Reporting multiple failures at once)
import { Schema } from "effect"
const schema = Schema.Struct({ a: Schema.Finite, b: Schema.Finite, c: Schema.Finite }).check(
Schema.makeFilter((o) => {
const issues: Array<Schema.FilterIssue> = []
if (o.a > 0) {
if (o.b <= 0) issues.push({ path: ["b"], issue: "b must be greater than 0" })
if (o.c <= 0) issues.push({ path: ["c"], issue: "c must be greater than 0" })
}
return issues
})
)
console.log(String(Schema.decodeUnknownExit(schema)({ a: 1, b: 0, c: 0 })))
// Failure(Cause([Fail(SchemaError: b must be greater than 0
// at ["b"]
// c must be greater than 0
// at ["c"])]))

Annotations.Augment.expected?: string | undefinedHuman-readable description of what a value is expected to satisfy.
Details
For filter and refinement failures, the default formatter uses
message first, then expected, and finally falls back to <filter>.
Use this to name a failed filter in the default message:
Expected <expected>, got <actual>.
expected: `a value less than ${const formatter: anyformatter(exclusiveMaximum: TexclusiveMaximum)}`,

Optional hints used by arbitrary derivation for this filter.
Details
The same annotation can be attached to a single filter or a
FilterGroup. Group hints apply to the same schema node while child
filters are still collected and checked normally.
