Implementations

impl FlexrayClusterSettings

pub fn new() -> Self

Create a new FlexrayClusterSettings object with default values

pub fn verify(&self) -> bool

Check the plausibility of the parameter values

Returns true if no problem was detected, of false if a problem was found. The checks performed by this function are not comprehensive. Some problems may remain undetected.

Example

let mut settings = FlexrayClusterSettings::default();
settings.macro_per_cycle = 1111;
assert!(!settings.verify())

Trait Implementations

impl Clone for FlexrayClusterSettings

fn clone(&self) -> FlexrayClusterSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlexrayClusterSettings

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

Formats the value using the given formatter.

impl Default for FlexrayClusterSettings

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FlexrayClusterSettings

fn eq(&self, other: &FlexrayClusterSettings) -> 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.
