Package: effect
Module: Filter

Filter.equals

Creates a filter that only passes values equal to the specified value using structural equality.

When to use

Use to accept inputs that are structurally equal to a known expected value while staying in a composable Filter / Result pipeline.

Details

Delegates to Equal.equals. On success it returns Result.succeed(value); on failure it returns Result.fail(input).

See

• equalsStrict for JavaScript === matching instead of structural equality
• Equal.equals for the underlying structural equality semantics

Signature

declare const equals: <const A, Input = unknown>(value: A) => Filter<Input, A, EqualsWith<Input, A, A, Exclude<Input, A>>>
