Struct DecodePolicy 

pub struct DecodePolicy { /* private fields */ }

Controls which otherwise valid tar features member decoding may accept.

See each configuration API for its default.

Implementations

impl DecodePolicy

pub fn allow_gnu(self, allow: bool) -> Self

Configures whether archives in the GNU framing family may be decoded.

GNU tar archives are allowed by default.

Users who wish to parse strictly pax-confirming tar archives may wish to disable this setting.

pub fn allow_all_nul_numeric_fields(self, allow: bool) -> Self

Configures whether wholly NUL numeric metadata fields may be accepted.

This compatibility option applies to the ordinary header’s mode, uid, gid, and mtime fields in both pax/ustar and GNU archives. It is enabled by default. When enabled, a wholly NUL field is represented as missing; every other value must be a valid numeric encoding for its archive family.

pub fn max_gnu_extension_size(self, max_gnu_extension_size: u64) -> Self

Configures the maximum payload size accepted for one GNU metadata extension.

The limit applies independently to long-name and long-link extensions. An extension that declares a larger payload is rejected before its payload is consumed. The default is DEFAULT_MAX_GNU_EXTENSION_SIZE. Setting the limit to zero rejects every nonempty GNU extension. Setting it to u64::MAX permits unbounded metadata buffering.

pub fn pax_policy(self, policy: PaxDecodePolicy) -> Self

Configures the accepted pax feature subset.
