Enum ParameterRegisterError 

pub enum ParameterRegisterError {
    NameLength,
    NameConversion,
    Storage(StorageError),
    Invalid,
    LockedHal,
    Memory,
}

Parameter registration error

Variants

NameLength

Parameter name is too long

The maximum length is dictated by the HAL_NAME_LEN constant

NameConversion

Parameter name could not be converted to C string

Storage(StorageError)

An error occurred allocating the HAL shared memory storage backing the parameter

Invalid

An error occurred in the LinuxCNC HAL functions

This variant is often returned when a HAL function returns EINVAL. This error code is returned for various different reasons. Check the LinuxCNC logs for error messages.

LockedHal

The HAL is locked

Resources cannot be registered after a component is created

Memory

There is not enough free memory available to allocate storage for this parameter

Trait Implementations

impl Debug for ParameterRegisterError

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

Formats the value using the given formatter.

impl Display for ParameterRegisterError

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

Formats the value using the given formatter.

impl Error for ParameterRegisterError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ParameterRegisterError> for ResourcesError

fn from(e: ParameterRegisterError) -> Self

Converts to this type from the input type.

impl PartialEq for ParameterRegisterError

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