21:T4ca,Given a schema Schema and a key key: K, this function extracts a specific field from the A type, producing a new schema that represents a transformation from the { readonly [key]: I[K] } type to A[K]. Signature ```typescript export declare const pluck: { ( key: K, ): (schema: Schema) => Schema< A[K], { readonly [P in K]: I[P] }, R > ( schema: Schema, key: K, ): Schema< A[K], { readonly [P in K]: I[P] }, R > } ``` Example import * as S from "@effect/schema/Schema" // --------------------------------------------- // use case: pull out a single field from a // struct through a transformation // --------------------------------------------- const mytable = S.Struct({ column1: S.NumberFromString, column2: S.Number }) // const pullOutColumn: S.Schema const pullOutColumn = mytable.pipe(S.pluck("column1")) console.log( S.decodeUnknownEither(S.Array(pullOutColumn))([ { column1: "1", column2: 100 }, { column1: "2", column2: 300 } ]) ) // Output: { _id: 'Either', _tag: 'Right', right: [ 1, 2 ] }22:T4ca,Given a schema Schema and a key key: K, this function extracts a specific field from the A type, producing a new schema that represents a transformation from the { readonly [key]: I[K] } type to A[K].
