Struct InvalidParameterCount

pub struct InvalidParameterCount {
    pub actual: usize,
    pub expected: ExpectedCount,
}

The received message has an invalid or unexpected parameter count.

Fields

actual: usize

The actual parameter count.

expected: ExpectedCount

The expected parameter count.

Implementations

impl InvalidParameterCount

pub fn check(actual: usize, expected: usize) -> Result<(), Self>

Check if the parameter count matches the expected count.

pub fn check_max(actual: usize, max: usize) -> Result<(), Self>

Check if the parameter count is at or below the max count.

Trait Implementations

impl Clone for InvalidParameterCount

fn clone(&self) -> InvalidParameterCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidParameterCount

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

Formats the value using the given formatter.

impl Display for InvalidParameterCount

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

Formats the value using the given formatter.

impl Error for InvalidParameterCount

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<InvalidParameterCount> for InvalidMessage

fn from(other: InvalidParameterCount) -> Self

Converts to this type from the input type.

impl From<InvalidParameterCount> for ReadError

fn from(other: InvalidParameterCount) -> Self

Converts to this type from the input type.

impl From<InvalidParameterCount> for TransferError

fn from(other: InvalidParameterCount) -> Self

Converts to this type from the input type.

impl PartialEq for InvalidParameterCount

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