[−][src]Enum sequoia_openpgp::types::CompressionAlgorithm
The OpenPGP compression algorithms as defined in Section 9.3 of RFC 4880.
Note: This enum cannot be exhaustively matched to allow future extensions.
Examples
Use CompressionAlgorithm
to set the preferred compressions algorithms on
a signature:
use sequoia_openpgp as openpgp; use openpgp::packet::signature::SignatureBuilder; use openpgp::types::{HashAlgorithm, CompressionAlgorithm, SignatureType}; let mut builder = SignatureBuilder::new(SignatureType::DirectKey) .set_hash_algo(HashAlgorithm::SHA512) .set_preferred_compression_algorithms(vec![ CompressionAlgorithm::Zlib, CompressionAlgorithm::BZip2, ])?;
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.
Null compression.
DEFLATE Compressed Data.
See RFC 1951 for details. Section 9.3 of RFC 4880 recommends that this algorithm should be implemented.
ZLIB Compressed Data.
See RFC 1950 for details.
bzip2
Private(u8)
Private compression algorithm identifier.
Unknown(u8)
Unknown compression algorithm identifier.
Implementations
impl CompressionAlgorithm
[src]
pub fn is_supported(&self) -> bool
[src]
Returns whether this algorithm is supported.
Examples
use sequoia_openpgp as openpgp; use openpgp::types::CompressionAlgorithm; assert!(CompressionAlgorithm::Uncompressed.is_supported()); assert!(CompressionAlgorithm::Zip.is_supported()); assert!(!CompressionAlgorithm::Private(101).is_supported());
