Struct apple_codesign::RequirementBlob

pub struct RequirementBlob<'a> {
    pub data: Cow<'a, [u8]>,
}

Represents a Requirement blob.

csreq -b will emit instances of this blob, header magic and all. So data generated by csreq -b can be fed into [RequirementBlob.from_blob_bytes] to obtain an instance.

Fields

data: Cow<'a, [u8]>

Implementations

impl<'a> RequirementBlob<'a>

pub fn to_owned(&self) -> RequirementBlob<'static>

pub fn parse_expressions(
    &self
) -> Result<CodeRequirements<'_>, AppleCodesignError>

Parse the binary data in this blob into Code Requirement expressions.
