}Expand description
Provides common features for a parsed blob type.
Required Methods§
Sourcefn from_blob_bytes(data: &'a [u8]) -> Result<Self, AppleCodesignError>
fn from_blob_bytes(data: &'a [u8]) -> Result<Self, AppleCodesignError>
Attempt to construct an instance by parsing a bytes slice.
The slice begins with the 8 byte blob header denoting the magic and length.
Sourcefn serialize_payload(&self) -> Result<Vec<u8>, AppleCodesignError>
fn serialize_payload(&self) -> Result<Vec<u8>, AppleCodesignError>
Serialize the payload of this blob to bytes.
Does not include the magic or length header fields common to blobs.
Provided Methods§
Sourcefn to_blob_bytes(&self) -> Result<Vec<u8>, AppleCodesignError>
fn to_blob_bytes(&self) -> Result<Vec<u8>, AppleCodesignError>
Serialize this blob to bytes.
This is Blob::serialize_payload with the blob magic and length prepended.
Sourcefn digest_with(
&self,
hash_type: DigestType,
) -> Result<Vec<u8>, AppleCodesignError>
fn digest_with( &self, hash_type: DigestType, ) -> Result<Vec<u8>, AppleCodesignError>
Obtain the digest of the blob using the specified hasher.
Default implementation calls Blob::to_blob_bytes and digests that, which should always be correct.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
