Struct EncodedEnvironmentConstraints 

pub struct EncodedEnvironmentConstraints {
    pub ccat: u64,
    pub comp: u64,
    pub requirements: Dictionary,
    pub vers: u64,
}

Represents the DER encoded form of environment constraints.

Instances can be converted into a Value using .into().

Fields

ccat: u64

We’re not sure what this is.

Value always appears to be 0.

comp: u64

We’re not sure what this is.

Value always appears to be 1.

We hypothesize it might be a compatibility version number.

requirements: Dictionary

The user-provided constraints, as a mapping.

vers: u64

We’re not sure what this is.

Value always appears to be 1.

We hypothesize it is a version number.

Implementations

impl EncodedEnvironmentConstraints

pub fn from_der(data: impl AsRef<[u8]>) -> Result<Self>

Attempt to decode an instance from DER.

pub fn from_requirements_plist(value: Value) -> Result<Self>

Obtain an instance from a requirements plist.

pub fn from_requirements_plist_file(path: impl AsRef<Path>) -> Result<Self>

Attempt to construct an instance by reading requirements plist data from a file.

Source file can be XML or binary encoding.

pub fn der_encode(&self) -> Result<Vec<u8>>

Encode the instance to DER.

pub fn requirements_plist(&self) -> Value

Obtain just the requirements as a plist Value.

Trait Implementations

impl Clone for EncodedEnvironmentConstraints

fn clone(&self) -> EncodedEnvironmentConstraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncodedEnvironmentConstraints

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

Formats the value using the given formatter.

impl Default for EncodedEnvironmentConstraints

fn default() -> Self

Returns the “default value” for a type.

impl From<EncodedEnvironmentConstraints> for Value

fn from(value: EncodedEnvironmentConstraints) -> Self

Converts to this type from the input type.

impl TryFrom<Value> for EncodedEnvironmentConstraints

type Error = AppleCodesignError

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.
