Toml.FromValue.Generic

Use genericParseTable to derive a ParseTable using the field names of a record. This can be combined with parseTableFromValue to derive a FromValue instance.

class GParseTable f where

Supports conversion of product types with field selector names to TOML values.

Methods

gParseTable :: (f a -> ParseTable b) -> ParseTable b

Convert a value and apply the continuation to the result.
