Rust representation for Decimal values.
This is not a representation of Parquet physical type, but rather a wrapper for
DECIMAL logical type, and serves as container for raw parts of decimal values:
unscaled value in bytes, precision and scale.
Fields of Int32

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
