Struct BlobEntry

pub struct BlobEntry<'a> {
    pub index: usize,
    pub slot: CodeSigningSlot,
    pub offset: usize,
    pub magic: CodeSigningMagic,
    pub length: usize,
    pub data: &'a [u8],
}

Represents a single blob as defined by a SuperBlob index entry.

Instances have copies of their own index info, including the relative order, slot type, and start offset within the SuperBlob.

The blob data is unparsed in this type. The blob payloads can be turned into ParsedBlob via .try_into().

Fields

index: usize

Our blob index within the SuperBlob.

slot: CodeSigningSlot

The slot type.

offset: usize

Our start offset within the SuperBlob.

First byte is start of our magic.

magic: CodeSigningMagic

The magic value appearing at the beginning of the blob.

length: usize

The length of the blob payload.

data: &'a [u8]

The raw data in this blob, including magic and length.

Implementations

impl<'a> BlobEntry<'a>

pub fn into_parsed_blob(self) -> Result<ParsedBlob<'a>, AppleCodesignError>

Attempt to convert to a ParsedBlob.

pub fn payload(&self) -> Result<&'a [u8], AppleCodesignError>

Obtain the payload of this blob.

This is the data in the blob without the blob header.

pub fn digest_with( &self, hash: DigestType, ) -> Result<Vec<u8>, AppleCodesignError>

Compute the content digest of this blob using the specified hash type.

Trait Implementations

impl<'a> Clone for BlobEntry<'a>

fn clone(&self) -> BlobEntry<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for BlobEntry<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&BlobEntry<'a>> for BlobDescription

fn from(entry: &BlobEntry<'a>) -> Self

Converts to this type from the input type.

impl<'a> TryFrom<BlobEntry<'a>> for ParsedBlob<'a>

type Error = AppleCodesignError

The type returned in the event of a conversion error.

fn try_from(blob_entry: BlobEntry<'a>) -> Result<Self, Self::Error>

Performs the conversion.
