Encoder

Encode a value of type A, yielding a list of Postgres text-formatted strings, lifted to Option to handle NULL values. Encoding failures raise unrecoverable errors.

Given an initial parameter index, yield a hunk of sql containing placeholders, and a new index.

Types of encoded fields, in order.

Contramap inputs from a new type B, yielding an Encoder[B].

Derive an encoder for a list of size n that expands to a comma-separated list of placeholders.

Derive an encoder for the specified list. This is equivalent to list(as.length) but the resulting encoder can only encode the exact list that it was passed. Prefer this overload when possible because it lessens the possibility of attempting to encode a list of the wrong length.

Oids of types, or mismatches.

Encoder is semigroupal: a pair of encoders make a encoder for a pair.

Returns an encoder that redacts encoded values.

Derive an equivalent encoder for a row type; i.e., its placeholders will be surrounded by parens.

Shorthand for product.

Adapt this Encoder from twiddle-list type A to isomorphic case-class type B.
