Enum NativeEncodingPolicy 

#[non_exhaustive]
pub enum NativeEncodingPolicy {
    RejectUnknown,
    AssumeUtf8,
}

Controls how a native CHARSXP is interpreted when the RDS header field is absent, which means format 2. Parsing retains bytes lazily for RStr values: conversion by crate::RStr::as_str or a typed view then performs validation or rejection. A SYMSXP print name is converted during parsing instead, so a symbol name that cannot be decoded fails immediately with crate::Error::InvalidSymbolName under either policy.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RejectUnknown

Preserve bytes for retained RStr values without assuming an encoding; conversion later rejects non-ASCII native strings in format 2 when no header encoding is available. SYMSXP print names are decoded during parsing.

AssumeUtf8

Treat native strings as UTF-8 in format 2 when the header has no encoding, for callers with an external UTF-8 contract. Conversion later validates retained RStr bytes without lossy replacement; SYMSXP print names are decoded during parsing.
