Struct SecCodeSignatureFlags

#[repr(transparent)]
pub struct SecCodeSignatureFlags(pub u32);

Available on crate feature CSCommon only.

This is the type of option flags that can be embedded in a code signature during signing, and that govern the use of the signature thereafter. Some of these flags can be set through the codesign(1) command’s –options argument; some are set implicitly based on signing circumstances; and all can be set with the kSecCodeSignerFlags item of a signing information dictionary.

Indicates that the code may act as a host that controls and supervises guest code. If this flag is not set in a code signature, the code is never considered eligible to be a host, and any attempt to act like one will be ignored or rejected.

The code has been sealed without a signing identity. No identity may be retrieved from it, and any code requirement placing restrictions on the signing identity will fail. This flag is set by the code signing API and cannot be set explicitly.

Implicitly set the “hard” status bit for the code when it starts running. This bit indicates that the code prefers to be denied access to a resource if gaining such access would cause its invalidation. Since the hard bit is sticky, setting this option bit guarantees that the code will always have it set.

Implicitly set the “kill” status bit for the code when it starts running. This bit indicates that the code wishes to be terminated with prejudice if it is ever invalidated. Since the kill bit is sticky, setting this option bit guarantees that the code will always be dynamically valid, since it will die immediately if it becomes invalid.

Forces the kSecCSConsiderExpiration flag on all validations of the code.

Instructs the kernel to apply runtime hardening policies as required by the hardened runtime version

The code was automatically signed by the linker. This signature should be ignored in any new signing operation.

Get a flags value with all bits unset.

The returned value is exactly the bits set in this flags value.

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

pub fn insert(&mut self, other: Self)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Self)

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl SecCodeSignatureFlags

pub const fn iter(&self) -> Iter<SecCodeSignatureFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<SecCodeSignatureFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
