Struct ConfigurationField 

pub struct ConfigurationField { /* private fields */ }

Configuration Field (CF) - EN 13757-7:2018 Clause 7.5.8, Table 18

The configuration field consists of two bytes containing information about the applied Security mode. The Security mode defines:

• applied set of security mechanisms
• content of other bits in the configuration field
• presence, length and content of configuration field extension (CFE)
• number, length and content of optional TPL-header/trailer fields

Bit Layout (Table 18)

• Bits 15-13: Security mode specific (X)
• Bits 12-8: Security mode bits (M) - 5 bits defining the security mode
• Bits 7-0: Security mode specific (X)

The decoding of bits marked “X” depends on the selected Security mode.

Implementations

impl ConfigurationField

pub const fn from_bytes(lsb: u8, msb: u8) -> Self

Create a Configuration Field from two bytes

Arguments

• lsb - Lower byte (bits 7-0)
• msb - Upper byte (bits 15-8)

pub const fn raw(&self) -> u16

Get the raw 16-bit value

pub const fn security_mode(&self) -> SecurityMode

Get the Security mode (bits 12-8, 5 bits)

The Security mode defines the applied set of security mechanisms. See EN 13757-7:2018 Table 19 for Security mode definitions.

pub const fn mode_specific_lower(&self) -> u8

Get the lower mode-specific byte (bits 7-0)

The meaning of these bits depends on the selected Security mode.

pub const fn mode_specific_upper(&self) -> u8

Get the upper mode-specific bits (bits 15-13)

The meaning of these bits depends on the selected Security mode.

Trait Implementations

impl Clone for ConfigurationField

fn clone(&self) -> ConfigurationField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigurationField

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

Formats the value using the given formatter.

impl From<ConfigurationField> for u16

fn from(cf: ConfigurationField) -> Self

Converts to this type from the input type.

impl From<u16> for ConfigurationField

fn from(value: u16) -> Self

Converts to this type from the input type.

impl Hash for ConfigurationField

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConfigurationField

fn eq(&self, other: &ConfigurationField) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
